The alkaloid (+)-ribasine was synthesized by stereocontrolled addition of substituted alpha-lithium-o-toluate 6d to enantiomerically pure (R)-N-(9-phenylfluoren-9-yl)-2-amino-5,6-(methylenedioxy)indan-1-one [(+)-5]. Aminoindanone (+)-5 was prepared from amino acid (-)-15 obtained by diastereoselective alkylation of a chiral glycine enolate synthon. (C) 1999 Elsevier Science Ltd. All rights reserved.
