Abstract

Nazarov reactions Intercepted by (4 + 3) Cycloadditions with Oxygen-SubstitutedDienes. -An oxyallyl cation, generated by Nazarov reaction of an allenyl vinyl ketone, is trapped by regioselective cycloaddition with 2-siloxy-1,3-butadienes to give bicyclo[4.2.1]nonane derivatives. -(LEFORT, F.
