Abstract

A ceramide transporter protein (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.
