Abstract
A number of chiral C-1-symmetric 1,10-phenanthrolines derived from naturall y occurring ketones were assessed in the enantioselective palladium catalyz ed allylic alkylation of 1,3-diphenylprop-2-enyl acetate with dimethylmalon ate. Enantioselectivity up to 96% was obtained with a new 1,10-phenanthroli ne derived from 5 alpha-cholestan-4-one. (C) 2000 Elsevier Science B.V. All rights reserved.
