ChemInform Abstract: 1,4-Diastereoselectivity in the Addition of Allylstannanes to 1-Alkyl- 2-oxocyclohex-3-eneacetic Acid Methyl Esters.
Abstract
The cyclohexanones (I) are substituted and dehydrogenated to give the cyclohexenoneacetates (II).
ChemInform Abstract
The cyclohexanones (I) are substituted and dehydrogenated to give the cyclohexenoneacetates (II). These react with the allylic trimethylsilanes and tributylstannanes (III) in the presence of Lewis acids, producing mainly the adducts (IV), together with the stereoisomers (V).
