• Carbohydrates as chiral templates: diastereoselective synthesis of N-glycosyl-N-homoallylamines and .beta.-amino acids from imines

  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.
