Regioselective lateral or vinyl C–H lithiation/1,5-retro-Brook rearrangement via quinolyl or pyridyl ring directed deprotonation
摘要:
A regioselective lateral or vinyl C-H lithiation/1,5-retro-Brook rearrangement via quinolyl or pyridyl ring directed deprotonation has been developed. 16 examples were tested and the corresponding alkyl silanes and E-vinyl silanes were obtained in moderate to good yields.
