We have achieved a total synthesis of apratoxin A in which thiazoline formation was accomplished from the moCys containing amide 4 using PPh 3(O)/Tf2O. Deprotection of the Troc and allyl ester in 17, coupling with tripeptide 3, and deprotection of the allyl ester and the Fmoc, followed by macrolactamization provided apratoxin A (1).
