摘要：
The intramolecular [2+2] photocycloaddition of 2-acyloxy-2-3-hexenoylcyclohexenones has been shown to be highly diastereoselective. The cycloadditions produce exclusively cis fused products and the sense and level of selectivity is consistent with a molecular mechanics model for initial bond formation in the stepwise cycloaddition.
