摘要
4-溴-2-氟苯基氰经格氏反应得到4-溴-2-氟苯乙酮,先保护羰基,再经格氏反应和二羟硼基取代、溴代制得4-(2-溴乙酰基)-3-氟苯硼酸,总收率54%。
4-(2-Bromoacetyl)-3-fluorophenylboronic acid was synthesized from 4-bromo-2-fluorobenzonitrile by Grignard reaction, protection of carbonyl with ethanediol, Grignard reaction and substitution by borono group to give 4-acetyl-3-fluorophenylboric acid followed by bromination with an overall yield of 54%.
