An efficient and regioselective electrophilic bromolactonization of cyclopropylmethyl diesters using triphenylphosphine sulfide (Ph3PS) or diphenyl selenide (Ph2Se) as the Lewis basic chalcogenide catalyst has been developed. It was observed that Ph3PS favored the formation of anti-diastereomer and yielded the multi-functional γ-lactones. Interestingly, the diastereoselectivity was reversed when using Ph2Se as a catalyst where the syn-product instead of the anti-product was favored. (Figure presented.).

A general and cost-effective route has been developed to synthesize 1-heteroarylsubstituted cycloalkylamines from readily available heteroarylacetate in good yields. This synthesis features a LHMDS promoted cyclization and one-pot hydrolysis/Curtius rearr
