A stereoselective route to vicinally substituted cyclopentane- and cyclobutane-carboxylates
Abstract
Intramolecular alkylation of the enolates derived from the esters (3) and (7) stereoselectively afforded the cyclopentanecarboxylate (4) and the cyclobutanecarboxylate (8), respectively; compound (8) is a potential intermediate for the synthesis of (±)-fragranol (10).
