An Enzymatic Approach to the Desymmetrization of Disubstituted Pyrrolines
摘要:
The enzymatic desymmetrization of 2,2- and 2,5-disubstituted pyrroline compounds is reported in a procedure which gives access to both enantiomers in excellent enantiomeric excess and good yield. The enzyme reaction precursors are formed easily from two readily available substituted pyrroles using both ammonia ( Na/NH3) and ammonia-free ( Li/DBB) Birch reduction conditions.
