Stereoselective synthesis of dihydropyrone-containing marine natural products. Total synthesis and structural elucidation of (-)-membrenone-C.

[figure: see text] Three diastereomers of membrenone-C were separately prepared using a common two directional chain extending synthetic strategy. This has established the absolute and relative configuration of the natural product to be as shown in the fo

Studies in Polypropionate Synthesis: A General Approach to the Synthesis of Stereopentads.

A general protocol for the synthesis of specific isomers of the stereopentad 1 from the α-chiral ethyl ketones (R)- and (S)-2 has been developed.From (S)-2, this involves stepwise elaboration of each of the three aldol adducts 3, 4 and 5 by stereoselectiv
