Synthetic studies on bryostatins, antineoplastic metabolites: Convergent synthesis of the C1-C16 fragment shared by all of the bryostatin family
摘要:
The C1-C-16 fragment of bryostatins could successfully be synthesized by tandem connection of the appropriate three fragments and effective introduCtion of the alpha,beta-unsaturated esters at the C-13 position.

The C1-C9 segment of epothilons was generated by an aldol reaction between chiral aldehyde 3 and ethyl ketone 4. Removal of the TBS protecting groups and debenzylation generated spiro ketal 13 which was analyzed by X-ray crystallography. (C) 1997 Elsevier Science Ltd.
