from 1-(2-furyl)ethanol using modified Piancatelli rearrangement and enzymatic kinetic resolution of the racemate was developed. An application of O-protected derivatives of 4-hydroxy-2-methylcyclopent-2-en-1-one to terpenoid synthesis through tandem conjugate addition of allyl-metal reagents, enolate trapping, and consecutive Mukaiyama–Michael addition was studied. An optically active azulene derivative
开发了一种通过修饰的Piancatelli重排和消旋体的酶促动力学拆分从1-(2-呋喃基)乙醇制备(S)-4-羟基-2-甲基环戊-2-烯-1-酮的方法。通过串联共轭添加烯丙基金属试剂,烯醇盐捕集和连续Mukaiyama-Michael加成反应,研究了O-保护的4-羟基-2-甲基环戊-2-烯-1-酮在萜类化合物合成中的应用。有效地合成了可用于类萜合成的旋光性z青烯衍生物。
