2-Bromo-3-methoxycyclohex-2-enone, a New Reagent for the α-Arylation of Lactams
Shepherd, Robin G.,White, Alan C.
, p. 2153 - 2156 (2007/10/02)
We report efficient syntheses of 2-bromo and 2-chloro-3-methoxycyclohex-2-enone and their use as m-hydroxyphenyl cation synthons for the α-arylation of lactams.The sequence has been used to synthesize the analgesic drug meptazinol.
