Reactivite des acylaldocetenes dans la cycloaddition intramoleculaire
TETRAHEDRON(1976)
摘要
The reactivity of acylaldoketenes, short-lived species generated by flash thermolysis of ϵ-ethylenic β-ketoesters, in [2 + 2] intramolecular cycloaddition reactions, has been examined. The observed regiospecificity can be rationalized by frontier orbital theory.
