  Reactions of anions derived from chiral nonracemic allyl, crotyl, and cinnamyl bicyclic C(2)-symmetrical phosphonamides with alpha, beta-unsaturated cyclic ketones, esters, lactones, and lactams take place at the gamma-position of the reagents. The products are diastereomerically pure or enriched beta-substituted carbonyl compounds. The method also provides easy access to vicinal substitution of as

  日期：1993.9

  Reactions of anions derived from chiral nonracemic allyl and crotyl bicyclic phosphonamides with alpha,beta-unsaturated cyclic ketones, esters, lactones, and lactams take place at the gamma-position of the reagents and lead to diastereomerically pure or highly enriched products of conjugate addition. The option to quench the corresponding enolates with various alkyl halides offers a versatile approach to vicinal substitution including the generation of quaternary carbon centers.
