Stereoselective total synthesis of ophiocerin D from d-xylose
摘要:
A stereoselective total synthesis of ophiocerin D is reported by a combination of a 'chiron' approach and an asymmetric synthesis, from D-Xylose. Of the four stereogenic centers, the vic diols C3/C4 and C5/C6 were obtained by Sharpless asymmetric dihydroxylation and from D-Xylose, respectively. (C) 2008 Elsevier Ltd. All rights reserved.

Four new tetrahydropyranderivatives called ophiocerins A-D (1-4) and a new africane sesquiterpenoid (ophioceric acid; 5) have been isolated from cultures of the aquatic fungus Ophioceras venezuelense, together with the known compound regiolone. The structures and relative stereochemistry of these compounds were determined by analysis of 1D and 2D NMR data, while absolute stereochemical assignments
