The present invention relates to the preparation of optically resolved chiral compounds of β-amino acid type active pharmaceutical ingredients (API), more specifically to β-aminobutyryl substituted compounds and especially β-aminobutyryl compounds having γ-bound aryl groups. The present invention more particularly relates to the preparation of enantiomerically enriched chiral compounds useful as intermediates for the preparation of anti-diabetic agents, preferably sitagliptin.
本发明涉及制备β-氨基酸类活性药物成分(API)的光学分辨手性化合物,更具体地涉及β-氨基丁酰取代化合物,特别是具有γ-键合芳基基团的β-氨基丁酰化合物的制备。本发明更具体地涉及制备对映体富集的手性化合物,用作制备抗糖尿病药物的中间体,优选为西格列汀。
