Preparation of (6R)- and (6S)-(1R,4R)-6-Methyl-2-(p-toluenesulfonyl)-5-phenylmethyl-2,5-diazabicyclo[2.2.1]heptanes, Intermediates in a Synthesis of New Quinolones
摘要:
An efficient chiral synthesis of both diastereoisomers (2a) and (2b) was performed using trans-4-hydroxy-L-proline as starting material. These bridged piperazines were used in the preparation of quinolones.
