Michael addition of secondary amines 1b–1g onto chiral acetylenic sulfoxides 2 followed by acid induced cyclization afforded structures of tetrahydroisoquinoline skeleton in high to moderate diastereoselectivity. Optical pure (S)-(−)-carnegine has been synthesized.
将手性乙炔亚砜2上的仲胺1b–1g迈克尔加成,然后酸诱导的环化反应,以高至中等非对映选择性提供了四氢异喹啉骨架的结构。光学纯的(S)-(-)-carnegine已合成。
