Stereoselective synthesis of C19–C27 fragment of bryostatin 11
摘要:
A convergent synthesis of C19-C27 fragment (2) of bryostatin-11 is described. The key steps involved in this approach are kinetic resolution, Grignard reaction, and Sharpless dihydroxylation. AIBN catalyzed radical cyclization strategy has been used for the first time to construct the six-membered pyran system. (C) 2014 Published by Elsevier Ltd.

A stereoselectivesynthesis of clonostachydiol is accomplished using readily available (±)-epichlorohydrin as a precursor. The synthesis involves direct and straightforward reactions such as Sharpless asymmetric epoxidation, iodination, stereoselective opening of epoxide with allylmagnesium chloride and Sharpless asymmetric dihydroxylation.
