(methallylidene)triphenylphosphorane with erythro-4-acetoxy-2,3-dimethylbutanal afforded erythro-2,3,6-trimethylhepta-4,6-dien-1-yl acetate as a mixture of E and Z isomers in a 85: 15 ratio. 1,4-cis-Hydrogenation of the conjugated diene system in the obtained isomeric mixture provided individual acetate of lasiol (erythro-2,3,6-trimethylhept-5-en-1-ol).
(亚甲基)三苯基正膦与赤式-4-乙酰氧基-2,3-二甲基丁醛的维蒂希反应得到赤式-2,3,6-三甲基庚-4,6-二烯-1-基乙酸酯,为E和Z异构体的混合物85:15 的比例。所得异构体混合物中的共轭二烯体系的1,4-顺式氢化提供了lasiol(赤式2,3,6-三甲基庚-5-en-1-ol)的单独乙酸酯。
