Abstract
AbstractA new convenient method for the asymmetric synthesis of the potent hypoglycemic agent KAD‐1229 was developed. The key step of this method is diasteroselective alkylation of 1 to give crude 2 (d.e.>93%) in good yield with the easily available Oppolzer's camphorsultam as chiral auxiliary. The overall yield of the product was 57%.
