Desireddi JR, Rao MM, Murahari KK, Nimmareddy RR, Mothe T, Lingala AK, Maiti B, Manchal R. Study of the β-oxygen effect in the Barton–McCombie reaction for the total synthesis of (4R,5R)-4-hydroxy-γ-decalactone (Japanese orange fly lactone): a carbohydrate based approach. RSC Adv 2022; 12:25520-25527. [PMID: 36199353 PMCID: PMC9449999 DOI: 10.1039/d2ra04531a] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Accepted: 08/15/2022] [Indexed: 11/21/2022] Open
Abstract
Efficient and facile synthesis of Japanese orange fly lactone (1) was achieved from a commercially available d-glucose by investigating the Barton–McCombie reaction with furanose anomeric isomers (12α, β) with an overall yield of 12.6%. During the course of this synthesis, the β-oxygen effect was discovered in the deoxygenation step at the C-3 position using the Barton–McCombie reaction, where the substrate allows the effect to operate in one of the isomers but not in the other. Under the same reaction conditions, xanthate derived from the β-furanose isomer affords a high yield of deoxygenated product, whereas the α-isomer produces a very low yield. The key transformations used were Wittig olefination, TEMPO mediated oxidation, and Barton–McCombie deoxygenation, resulting in a concise total synthesis of Japanese orange fly lactone (1). Our success will allow for further biological studies of this natural product, as well as opportunities for developing new potentially promising pheromones. The Japanese orange fly lactone was synthesised with a chiral pool approach using commercially available, starting material d-glucose. This synthesis encountered a dominant structurally functioning impact in the Barton–McCombie reaction known as the β-oxygen effect.![]()

Abstract
A practical and flexible strategy toward α-hydroxy-β-amino esters and amides, which are important biological motifs, based on an organocatalytic cross-aldol reaction of in situ-generated nitrosocarbonyl intermediates followed by hydrogenation is presented. The protocol features operational simplicity, high yields, a wide substrate scope, and high regio- and diastereoselectivity profiles. The utility of this method was showcased through the synthesis of bestatin analogues and indole formation.
