Formation of C₁₀-Aldimine in Sodium-initiated Reactions of Isoprene with Primary Amines

Abstract

The sodium-initiated reaction of isoprene with some primary amines was investigated. In particular, the reaction usi4g sterically hindered amines (t-butyl, s-butyl and isopropylamines)gave two kinds of C₁₀-aldimines (2-ethyl-2, 4-, and 2-ethyl-2, 5-dimethyl-4-hexeriyntlidene tbutylamine (6) and (5)), along with the normal adducts.
