摘要

Treatment of metallacycles 1 and 2 with electrophiles other than bromine provides a stereoselective route to a variety of functionalized cyclopentanes (Table I). Io Oxidation to the corresponding diols is carried out by bubbling dioxygen through the cyclized product (I5 min, room temperature) prior to hydrolytic workup.]] The straightforward synthesis of both cis- and trans-fused heterobicycles is illustrated in Table I by reactions with diphenyltin ...
