摘要

Discussion Two methanesulfonate groups seem essential to carry out this l, &elimination satisfactorily, since other leaving groups such as OH and OTHP brought about the formation of a mixture of products. Thus, the products from 18b were 37 and 38 in 70% and 23% yields, respectively, and 18c gave cyclopropane 19 (45%) and 39 (47%)(eq 10 and 11).
