Chemistry of acetylenic ethers 74: 1‐(dialkylamino)‐1‐alkynes from 1‐alkoxy‐1‐alkynes

Abstract

Abstract 1‐Alkynyl ethers, RCC‐O‐Alk (with R  alkyl), have been converted into the corresponding yneamines, RCC‐N‐(R′) 2 , in good yields (except when R  CH 3 ) by means of lithium dialkylamides, LiN‐(R′) 2 .
