Allylation of N,N-Acetal Derivatives Using Allyl Tin Regent in the Presence of Aluminum Chloride
摘要:
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.

Reactions of N-(α-benzotriazolylalkyl)-N,N-dialkylamines with the dialkylamine corresponding to the dialkylamino substituent afford symmetrical aminals in good yields. Treatment with other dialkylamines gives mixtures of the unsymmetrical and the two symmetrical aminals. Cross-over experiments of symmetrical aminals demonstrates interconversions involving iminium ions and that equilibria exist in the

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.
