The indium-mediated allylation of α-aminoaldehyde 3 from d-glucono-δ-lactone provided the syn-aminoalcohol with excellent diastereoselectivity. syn-Aminoalcohol was easily applied to the total syntheses of the potent glycosidase inhibitors; (+)-castanospermine and (+)-6-epicastanospermine.
铟介导的α-氨基醛3从D-葡萄糖-δ-内酯的亲核烯丙基化反应提供了优异的二元立体选择性合成的顺式氨基醇。顺式氨基醇很容易应用于强效糖苷酶抑制剂的总合成;(+)-卡斯塔诺斯珀明和(+)-6-去乙酰卡斯塔诺斯珀明。
