Beta-substituted and alpha,beta-disubstituted delta-oxo acids are synthetized with high enantiomeric excess from chiral 2-propenyl oxazolines 8 and 11, whilst 2-vinyl oxazolines 7 and 10 are less efficient asymmetric inductors.
New synthetic approaches to the oxahydrindane subunit of avermectins
Isoquinuclidine derivatives 9a, 9b, resulting from an asymmetric Diets Alder cycloaddition, afforded, after a two step sequence of reactions, functionalized cyclohexenes 11 and 31 precursors of the oxahydrindane subunit of Avermectins. (C) 1997 Elsevier Science Ltd.
