The first synthesis of a thermally stable, chiral allenic suIfoxide (2-exo-hydroxy-10-bornylsulfinyl)propa-1,2-diene, has been achieved. It was revealed that the sulfoxide would be stabilized to racemization by an intramolecular hydrogen-bond.
首次合成了热稳定的手性烯丙基亚砜(2-外型-羟基-10-
冰片亚砜基)丙-1,2-二烯。结果表明,亚砜可通过分子内氢键稳定为外消旋体。
