Diastereoselective azomethine ylide cycloadditions to unsaturated, chiral bicyclic lactams
摘要:
The levels of diastereoselection resulting from the 1,3-dipolar cycloaddition of chiral and achiral azomethine ylides 2(a-c) to chiral, unsaturated bicyclic lactams 1(a-f) are described in terms of steric factors.
