Abstract
Catalytic amounts of aminium salts induce the isomerization of alpha-ionone oxide, 5, affording 1,3,3-trimethyl 2-(3-oxo-1-buten-1-yl)cyclopent-1-ylcarbaldehydes 6a,b together with trace amounts of 2,4,4-trimetyl-3-(3-oxo-1-buten-1-yl)cyclohexanones 6c,d. Protic and Lewis acids-catalyzed reactions have also been comparatively studied.File in questo prodotto:
