Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

Two endogenous γ-lactones, 3-hydroxy-4-butanolide (I) and 2-hydroxy-4-hydrtoxymethyl-4-butanolide (II) have been identified as substances that enhance, resp., satiety and hunger by their effects on the feeding behavior and the central neurons of rats. All the stereoisomers of these two lactones were synthesized and their effects on the feeding behavior and humoral factors were assessed by infusion into the rat third cerebroventricle. Among four isomers, (2S,4S)-II was most effective in eliciting the feeding and caused potent hypoglycemia with hyperinsulinemia. (S)-I suppressed the food intake more potently than the antipode and caused humoral responses reciprocal to those of (2S,4S)-II. Thus, (S)-I and (2S,4S)-II are physiol. active forms for conveying intrinsic signals of satiety and hunger to neurons in the hypothalamus.

Compound: (R)-4-Hydroxydihydrofuran-2(3H)-one( cas:58081-05-3 ) is researched.Safety of (R)-4-Hydroxydihydrofuran-2(3H)-one.Dostie, Starr; Prevost, Michel; Mochirian, Philippe; Tanveer, Kashif; Andrella, Nicholas; Rostami, Ariana; Tambutet, Guillaume; Guindon, Yvan published the article 《Diastereoselective Synthesis of C2′-Fluorinated Nucleoside Analogues Using an Acyclic Approach》 about this compound( cas:58081-05-3 ) in Journal of Organic Chemistry. Keywords: C fluorinated nucleoside analog diastereoselective synthesis cyclization acyclic thioaminal. Let’s learn more about this compound (cas:58081-05-3).

Nucleoside analogs bearing a fluorine in the C2′-position have been synthesized by SN2-like cyclizations of acyclic thioaminal precursors. This strategy provides access to two scaffolds, D-1′,2′-cis-thiofuranosides and D-1′,2′-trans-furanosides, which are difficult to generate using the standard approach for nucleoside synthesis. The addition of silylated nucleobases onto model C2-fluorinated dithioacetal substrates resulted in 1,2-syn diastereoselectivity, which is consistent with the C2-F and S-alkyl moiety being in close proximity. A new series of analogs bearing a C3′ all-carbon quaternary center along with a C2′-F atom have also been synthesized using this approach and are being investigated as potential antimetabolites.
