Copper(I)-catalyzed coupling reaction of aryl boronic acids with N,O-acetals and N,N-aminals under atmosphere leading to α-aryl glycine derivatives and diarylmethylamine derivatives
摘要:
We demonstrated a copper(I)-catalyzed coupling reaction of aryl boronic acids with N,O-acetals and N,N-aminals leading to the synthesis of alpha-aryl glycines and diarylmethylamines. Under an ambient atmosphere, this catalytic system could be applied to the activation of a C(sp(3))-O bond of N,O-acetals with an ester and an aryl group, or without a coordinating substituent, as well as to a C(sp(3))-N bond of N,N-aminals.

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.

Allylation of N,N-acetal derivatives proceeded efficiently using allyl tin regent in the presence of aluminum chloride, giving homoallylamines in good yields. This allylation was applied for N,S-acetals to give the corresponding homoallylamines.
