Straightforward coordination-driven supramolecular chemistry preparation of a discrete solid-state luminescent Cu-4 polymetallic compact assembly based on conformationally flexible building blocks

The ditopic nitrile-capped 1,4-phenylenediacetonitrile linker L-3 featuring partial conformational flexibility was reacted with a flexible pre-assembled Cu(I) dimer stabilized by the bis(diphenyl-phosphino)methane dppm ligand along adaptive coordination-driven supramolecular assembling processes. It resulted in the selective and unexpected formation of a compact tetrametallic assembly associating two bimetallic building blocks with three ditopic linkers. The solid-state photophysical studies of this original Cu(I)-based assembly were analysed and showed its attractive luminescence properties.

Enantioselective Cyanoborylation of Allenes by N-Heterocyclic Carbene-Copper Catalysts

The simultaneous incorporation of both a cyano group and a boryl unit into the C=C double bonds of allenes in a regio- and stereoselective fashion is of much interest and importance but remains a significant challenge. We report herein a copper-catalyzed chemo-, regio-, and enantioselective cyanoborylation of allenes, which afforded a family of valuable enantiopure beta-boryl allyl nitriles. The high enantioselectivity was achieved by installing of appropriate substituents at the C2 and C6 positions of the naphthyl groups in our newly synthesized N-heterocyclic carbene (NHC) ligands. The reaction mechanism has been clarified by some stoichiometric reactions and computational studies. This work provides an inspiring example of the development of selective catalytic reactions for the synthesis of functional molecules through fine-tuning the ligands in catalysis.

ANALOGS OF THE MARINE IMMUNOSUPPRESSANT MICROCOLIN-A – PREPARATION AND BIOLOGICAL-ACTIVITY

A series of analogs of the immunosuppressive lipopeptide microcolin A has been prepared and evaluated for in vitro activity in the human and murine two-way mixed lymphocyte reaction. The compounds tested were obtained by semisynthetic modification and chemical degradation of the natural product. The relative potencies of these analogs suggest that the hydroxyproline and 5-methyl-3-pyrrolin-2-one portion of the molecule are important for immunosuppressive activity and that other structural elements may play an ancillary role. Methanolysis of microcolin A also led to a novel immunosuppressive lactone analog.

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.

ANALYTICAL INVESTIGATION OF THE FLAVOR OF CUPUACU (THEOBROMA-GRADIFLORUM SPRENG)

The Cupuacu (Theobroma grandiflorum Spreng.) tree, a relative of cocoa (Theobroma cacao L), is indigenous to Amazonia, Brazil. The pulp of its fruits is consumed e.g. in juices, ice creams or bakery fillings, especially in Brazilian Belem region. As a part of our ongoing project aimed at the investigation of less common tropical fruit flavors, the flavor of cupuacu pulp was analyzed. Flavor extracts were prepared by using vacuum distillation, solid phase extraction and simultaneous steam distillation-extraction (SDE). The concentrates were evaluated sensorially, and analyzed by means of GC-, GC/MS- and GC-O techniques. Several major to minor components of sensory importance for the cupuacu flavor were identified along with a number of trace constituents with very high flavor impact. The portion of short-chain acids, responsible for the typical acidic aspects of cupuacu flavor, is mainly associated with the fibrous part of the pulp, whereas the distillate is dominated by several esters. 2-Ethyl-5-methyl-4-hydroxy-3(2H)-furanone could be identified as an important trace component in the concentrate obtained by solid-phase extraction on RP-18 material. Thermal treatment of cupuacu pulp produced additionally a bread-like flavor impression, for which 2-acetyl-1-pyrrolin was found to be responsible.
