摘要:对于环丙烷环合成的碱催化加成-消除方法的立体化学,采用β γ不饱和苯基砜和αβ不饱和酯,已审查.的烯烃几何β γ不饱和砜被保留在产品中,和不饱和侧链和酯官能团出现反式围绕该环,具有相当大的立体选择性.另一方面,αβ-不饱和酯的双键的几何形状在阴离子加成产物中达到平衡.因此,基于原始αβ-不饱和酯的几何形状,在没有立体选择偏好的情况下产生了所得的环丙烷.这项工作已导致合成乙基2,2-二甲基-反式-3-[(1E,5 E)-2,6,10-三甲基十一碳烯-1,5,9-三烯基]环丙烷羧酸盐(40)和相应的环丙基甲醇(42),代表角鲨烯分子的一侧,和对c-2差向异构二萜类化合物2-[((e))-4,8-二甲基壬基-3,7-二烯基]-2-甲基-反式-3-(2-甲基丙-1-烯基)环丙烷羧酸酯(44)和(45)以及相应的醇(47)和(48),代表角鲨烯分子的另一侧.还研究了较低的异戊二烯.

标题 :Method of making teprenone
发明人：SAUCY GABRIEL G
摘要:The invention is directed to an efficient and economical method of making teprenone. Teprenone is synthesized by converting geranylgeraniol to teprenone by a novel route. The method of synthesis can begin with geranylgeraniol obtained from a biological source such as fermentation of a microorganism capable of producing geranylgeranyl or enzymatic synthesis in a cell free system to produce predominantly the 5E isomer of teprenone. The chemical synthesis proceeds with retention of configuration such that the teprenone produced has the isomeric configuration of the geranylgeraniol starting material.
