Selective formation of 2-acyloxy-1-oxospiro[4.n]alkanes by regio- and stereoselective rearrangement of α,β-epoxy acylates in bicyclo[n.3.0]alkane systems has been achieved; the effect of the acyloxy group and stereochemistry of the starting epoxides were studied. The reaction was successfully applied to the synthesis of an optically active chiral spiro compound.
