Zinc-Mediated Allylation and Alkylation of Aminals in the Presence of TMSCl and Diisopropylamine
摘要:
An alkylation of aminals with organozinc reagents derived from allyl bromide, benzyl bromide, alpha-bromoacetate, and alpha-bromonitrile proceeded efficiently in the presence of TMSCl and diisopropylamine. This reaction system was applied to the synthesis of an antispasmodic: butaverine.
