Stereoconvergent approach to each of the stereoisomeric hydroxydiquinanes based on the anionic [1,3] rearrangement of bicyclo[3.2.1]oct-6-en-2-ols

Autor: Masako Ueno, Tadao Uyehara, Toshio Sato, Hiroki Hashimoto, Katsura Seki

Publikováno v: Tetrahedron Letters. 40:511-514

The anionic [1,3] rearrangement of both stereoisomeric bicyclo[3.2.1]oct-6-en-2-ols by treatment with KN(TMS) 2 in toluene or in diglyme took place as a stereoconvergent route giving each of the stereoisomeric hydroxydiquinanes.
