nBusP-or cyanide-stabilized RCu.BF3 (R=Me, 4-Me-3-pentenyl) undergo efficient 1,4additions to neopentylether-shielded trans-enoates. Thus chiral B-substituted carboxylic acids e.g. (S)-citronellic acid were obtained in high e.e. (Schemes 2 and 4). Recently greater than 99% enantioselective C-C bond
