A Concise and Stereoselective Synthesis of Hydroxypyrrolidines: Rapid Synthesis of (+)-Preussin
摘要:
A convergent and stereoselective synthesis of 2,5-disubstituted 3-hydroxypyrrolidines has been developed that involves reductive annulation of beta-Iminochlorohydrins, which are readily available from beta-ketochlorohydrins, and provides rapid access to a variety of 2,5-syn-pyrrolidines. Application of this process to the concise (three-step) synthesis of the fungal metabolite (+)-preussin and analogues of this substance is reported.
