The reaction of cyclohexa-2,5-dienyl-1-methylaldehyde and optically pure 1,2-diaryl-1,2-diamine followed by intramolecular bromo-amination produced a one-pot discrimination of two olefins in the cyclohexane system, which was used for the asymmetric synthesis of (â)-γ-lycorane.
环己烯-2,5-二烯基-1-甲醛与光学纯1,2-二芳基-1,2-二胺的反应,再经过分子内溴氨化,产生了一锅法在环己烷体系中对两种烯烃的辨别,这一过程用于(â)-γ-利克贺因的不对称合成。
