Stereoselective Total Synthesis of Pectinolides A, C, and H

A simple and straightforward stereoselective total synthesis of Pectinolides A, C, and H is described. The synthesis has been started from commercially available (+)-diethyl l-tartrate and involves Ohira-Bestmann reaction, Corey-Bakshi-Shibata (CBS) reduction, and Still-Gennari olefination as key steps.

Large laboratory scale synthesis of (2S,3S)-2-(4-methoxybenzyloxy)-3,4-O- (3-pentylidene)-1,3,4-butantriol, a versatile chiral building block in natural product synthesis

(2S,3S)-2-(4-Methoxybenzyloxy)-3,4-O-(3-pentylidene)-1,3,4-butanetriol (3), a versatile chiral building block for an essential structural unit of complex natural products, was synthesized starting from dimethyl L-(+)- tartrate (5) on both a small scale and a large scale in good yield.
