Enantioselective total synthesis of (-)-Clavosolide A and B

Enantioselective total synthesis of (-)-clavosolide A and B was reported in full including the synthesis of proposed structure of (-)-clavosoldie A (1), revised structure of (-)-clavosoldie A (5), and revised structure of (-)-clavosoldie B (6). The relative and absolute stereochemistries of the natural products were confirmed unambiguously by comparing the optical rotation values and 1H and 13C NMR spectra of them.

Enantioselective total synthesis of (-)-clavosolide B

Enantioselective synthesis of 2, a revised structure for (-)-clavosolide B, was accomplished by a convergent approach, where syn-selective aldol, hydroxy-directed cyclopropanation, Mitsunobu inversion, Schmidt-type glycosylation, and macrolactonization re

Studies towards the synthesis of the β-D-Xyl-(1→ 3)-L-ara disaccharide moiety of OSW-1 from Ornithogalum saundersiae

The OSW-1 disaccharide having 2-O-p-methoxybenzoyl-β-D-xylopyranosyl- (1 → 3)-L-arabinopyranoside structure was obtained as the benzylated 4-O-acetyl derivative 19. Also, the 4,2′-di-O-acetate 18 was synthesized by a short synthetic approach. The arabinos
