Successful synthesis of the hindered 7-cis and 7,9-dicis isomers of 3-dehydroretinal from β-ionone is reported. The procedure, involving introduction of the hindered 7-cis geometry prior to the 3,4-double bond, should be applicable to preparation of other unknown isomers of Vitamin A2 aldehyde.
据报道,由β-紫罗兰酮成功合成了3-脱氢视黄醛的7-顺式和7,9-迪西斯受阻异构体。该方法涉及在3,4-双键之前引入受阻的7-顺式几何结构,应适用于制备其他未知的维生素A 2醛异构体。
