Synthesis of Fused Six-Membered Lactams to Isoxazole and Isoxazoline by Sequential Ugi Four-Component Reaction and Intramolecular Nitrile Oxide Cyclization

The advanced organic chemistry experiments describe the preparation of fused six-membered lactams to isoxazole and isoxazoline by employing Ugi four-component reaction (U-4CR) and intramolecular nitrile oxide cyclization (INOC) synthetic sequence. The experiments were carried out in 28 h (overnight for U-4CR) and 2 h (for INOC) using commercially available starting materials. The two-step reaction involves the in situ imine formation in the one-pot multicomponent reaction and in situ nitrile oxide formation in the INOC. The experiments are useful in the organic chemistry curriculum for the introduction of a onepot multicomponent reaction and 1,3-dipolar cycloaddition reactions.

Cyclocondensation of amidines with dimethyl acetylenedicarboxylate: A convenient entry into tetramic acids

Amidines undergo cyclocondensations with dimethyl acetylenedicarboxyl ate (DMAD) to give highly functionalized 5-dialkylamino-4-pyrrolin-3-ones. The products are crystalline, highly colored compounds that are uniquely functionalized and represent advanced intermediates in the construction of several other heterocyles, in particular the biologically active tetramic acids. The synthetic transformations of these compounds to tetramic acids are also described.

N-benzyl-5-hydroxy-3-pyrrolidin-2-one by hydrogen peroxide oxidation of n-benzyl-3-phenylseleno-2-pyrrolidinone

Using the known peroxide oxidation of N-benzyl-3-phenylseleno-2-pyrrolidinone with 30% hydrogen peroxide at – 5 degrees C after 3.5 h, we prepared the expected N-benzyl-3-pyrrolin-2-one. However, reaction with 30% hydrogen peroxide for 12 h (-5 degrees C -> ambient) gave the unexpected product N-benzyl-5-hydroxy-3-pyrrolidin2-one in 84% isolated yield. This procedure is a new synthetic route to N-benzyl-5hydroxy-3-pyrrolidin-2-one.

Metabolism of furans in vitro: Ipomeanine and 4-ipomeanol

Ipomeanine (IPN), 4-ipomeanol (4-IPO), 1-ipomeanol (1-IPO), and 1,4-ipomeadiol ( DIOL) are toxic 3-substituted furans found in mold-damaged sweet potatoes. IPN and 4-IPO are the most toxic, but all produce pulmonary toxicity in cattle and rodents, and 4-IPO induces hepatotoxicity in humans. These furans require metabolic activation to elicit toxicity, but the limited information obtained from previous metabolism studies prompted us to initiate the investigation reported here. Our initial studies of 4-IPO metabolism by rat liver microsomes demonstrated that the oxidation of 4-IPO to IPN and reduction to DIOL occurred and that more IPN was metabolized to a reactive species than 4-IPO or DIOL. Incubation of IPN and Gly produced a 2 ‘-pyrrolin-5 ‘-one adduct establishing that IPN was metabolized to an enedial. N-Acetylcysteine reacted with the 5 ‘-aldehyde of the enedial to give two 2 ‘,5 ‘-dihydro-2 ‘-hydroxyfurans stabilized by H bonding between the 2 ‘-OH and 3 ‘-keto group. Reaction of the enedial metabolite of IPN with one GSH gave several adducts including a pyrrole derived from the 1,2-addition of GSH to the 5 ‘-aldehyde as well as two tricyclic 2 ‘-pyrrolines derived from the 1,4-addition of GSH at the 4 ‘-position. The identities of the pyrrole and 2 ‘-pyrroline GSH adducts were confirmed by observation of structurally similar adducts from Cys conjugation with the enedial metabolite of IPN. Several minor adducts from the conjugation of the enedial metabolite of IPN with two GSH were also detected. Mono-GSH and bis-GSH adducts were derived from both the 1,2- and 1,4-addition of GSH to the enedial metabolite of 4-IPO in rat liver microsomal incubations of 4-IPO and GSH. Sequential oxidation of 4-IPO to IPN and then to the enedial metabolite followed by GSH conjugation also occurred in the 4-IPO incubations. The complex structures of the reaction products of the enedial with biological nucleophiles may explain why the many attempts to identify 4-IPO adducts to protein have not been successful.

Functional rearrangement of polychlorinated pyrrolidin-2-ones to 5-imino-lactams promoted by n-propylamine

The reaction of 4-methyl-pyrrolidin-2-ones, chlorinated at the C(3) and C(6) positions, with n-propylamine constitutes a new method for the preparation of 5-propylimino-pyrrolidin-2-ones or 3-pyrrolin-2-ones in generally good yields. The transformation involves a series of eliminations, substitutions and double bond shifts. This constitutes a remarkable example of a functional rearrangement. (C) 2004 Elsevier Ltd.

Nitrile Oxidation at a Ruthenium Complex leading to Intermolecular Imido Group Transfer

The oxidation of an acetonitrile ligand coordinated to ruthenium is explored in deuterated dimethyl sulfoxide by H-1 NMR spectroscopy. When oxidized with an iodosoarene oxygen atom transfer (OAT) reagent, kinetic studies demonstrate that the nitrile ligand does not dissociate before reacting. Instead, OAT to the central nitrile carbon is implicated (nitrile oxidation) and is further supported by the product of the reaction, N-acyldimethylsulfoximine. The N-acyldimethylsulfoximine likely formed by an imido group transfer reaction from ruthenium to the NMR solvent, and the product was synthesized independently to verify its identity in the reaction. This reaction represents the first time that a nitrile oxidation reaction has resulted in intermolecular imido group transfer to a substrate, presumably through a reactive ruthenium(IV)imido intermediate. This suggests that nitrile oxidation is a plausible route into reactive metal-imido intermediates for amination and aziridination reactions.

SOLEIL and ALMA views on prototypical organic nitriles: C2H5CN

The high resolution vibrational spectrum of ethyl cyanide (C2H5CN) has been investigated in the far-IR using synchrotron-based Fourier transform spectroscopy. The assignment was performed using the Automated Spectral Assignment Procedure (ASAP) allowing accurate rotational energy levels of the four lowest fundamental vibrations of the species, namely the v(13) = 1 @ 205.934099(8)cm(1), v(21) = 1 @ 212.141101(8)cm(1), v(20) = 1 @ 372.635293(15)cm(1), and v(12) = 1 @ 532.699617(16)cm(1) states, to be determined. The analysis not only confirms the applicability of the ASAP in the treatment of (dense) high-resolution infrared spectra but also reveals some of its limitations. Complementary to the infrared study, the pure rotational spectrum of C2H5CN was also studied in selected frequency ranges from 75 to 255 GHz. New observations of a prototypical high-mass star-forming region, G327.3-0.6, performed with the Atacama Large Millimeter Array show that vibrational satellites of C2H5CN can be very intense, of order several tens of Kelvin in units of brightness temperature.
