Epoxidation of alnus-5(10)-en-3β-yl acetate with m-chloroperbenzoic acid gave a 5α,10α-epoxide, treatment of which with boron trifluoride etherate afforded multiflora-5,8-dien-3β-yl acetate. On hydrogenation and hydrolysis, the diene gave isomultiflorenol.
alnus-5(10)-en-3β-yl 乙酸酯与间氯过苯甲酸环氧化得到 5α,10α-环氧化物,用三氟化硼醚合物处理得到 multiflora-5,8-dien-3β-yl 乙酸酯。在氢化和水解时,二烯得到异多花酚。
