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-
氨基酸型活性药物成分(A
PI)的光学分离手性化合物,更具体地涉及β-
氨基丁酰取代化合物,特别是具有γ-结合芳基的β-
氨基丁酰化合物。本发明更具体地涉及制备对手性富集的手性化合物,用作制备抗糖尿病药物的中间体,优选为席他格列汀。
