Relevant academic research and scientific papers

Asymmetric total synthesis of (+)-brefeldin A from (S)-lactate by triple chirality transfer process and nitrile oxide cycloaddition

A novel synthesis of (+)-brefeldin A (1) has been accomplished on the basis of triple chirality transfer methodology, intramolecular ester enolate alkylation, and both intra- and intermolecular nitrile oxide cycloaddition strategies.

A synthetic approach to (+)-brefeldin A

A unique 12-step scheme for the stereoselective synthesis of (+)- brefeldin A intermediate 2 starting from ethyl O-benzyl (S)-lactate (3) has been accomplished.
