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.
Key words
HPA-12 - gold - nitrone - 4-isoxazoline - stereoselective synthesis
