Diastereoselective synthesis of cis-1,2-disubstituted cyclopropanols and cyclopent-3-enols via SmI2 mediated C–N(Bt) bond cleavage

Abstract Diastereoselective synthesis of cis -1,2-disubstituted cyclopropanols and cyclopent-3-enols has been achieved from readily available β-benzotriazolyl ketones (β-Bt ketones) via a C–N(Bt) bond cleavage/cyclization process promoted by SmI 2 /HMPA.
