(CERT)-dependent ceramide-trafficking inhibitor, HPA-12, is efficiently synthesized using gold(I)-catalyzed cyclization of a propargylic N-hydroxylamine, which is prepared via a stereoselective nitrone–alkyne addition reaction. The resulting 4-isoxazoline is converted into a syn-1,3-amino alcohol through stereoselective reduction and reductive ring opening. A ceramide transporter protein (CERT)-dependent
摘要 使用金(I)催化的炔丙基N-羟胺的环化反应可有效合成神经酰胺转运蛋白(CERT)依赖性的神经酰胺贩运抑制剂HPA-12 ,后者是通过立体选择性硝酮-炔烃加成反应制备的。通过立体选择性还原和还原性开环将所得的4-异恶唑啉转化为合成-1,3-氨基醇。 使用金(I)催化的炔丙基N-羟胺的环化反应可有效合成神经酰胺转运蛋白(CERT)依赖性的神经酰胺贩运抑制剂HPA-12 ,后者是通过立体选择性硝酮-炔烃加成反应制备的。通过立体选择性还原和还原性开环将所得的4-异恶唑啉转化为合成-1,3-氨基醇。
