• High diastereoselective vinylogous Mannich reaction induced by O-pivaloylated d-galactosylamine as the chiral auxiliary: stereoselective synthesis of 8-arylazocan-2-one

  The diastereospecific formation of β-N-glycosidically linked α,β-unsaturated δ-amino aldehyde derivatives has been achieved with high yield via a vinylogous Mannich reaction. The reaction was performed by using a O-pivaloylated galactosyl amine as a chiral template and AlCl3 as a promoter in THF. (S)-8-(p-Nitrophenyl) azocan-2-one can be stereoselective synthesized from (S) ethyl 7-galactosylamino

• Carbohydrates as chiral templates: diastereoselective synthesis of N-glycosyl-N-homoallylamines and .beta.-amino acids from imines
  作者：Sabine Laschat、Horst Kunz

  日期：1991.9

  Complexing properties and chirality of carbohydrates were utilized in diastereoselective reactions of O-pivaloylated N-galactosylimines with allylsilanes and -stannanes. With allyltrimethylsilane in the presence of SnCl4, imines 2 of aromatic and heteroaromatic aldehydes were converted to homoallylamines 3, giving ratios of diastereomers higher than 7:1. No addition products derived from alpha-anomeric aromatic imines were formed. Aliphatic homoallylamines 3 were synthesized by using allyltributylstannane in the presence of SnCl4. Both alpha- and beta-anomeric aliphatic imines reacted with the allylstannane. They gave the same ratio of diastereomers and showed the same sense of asymmetric induction.
