摘要：

When the benzoate of (S)-(Z)-2-(5-(tert-butyldimethylsiloxy)-2-methylencyclohexyliden)-ethanol (5) is treated with 2.5 equivalents of Hg(OOCCF3)(2) in dry THF, a smooth and selective allylic hydroxylation occurs. The C-1 functionalized vitamin D A-ring synthon 6 is isolated in 65 to 70% yield in a single step.
