A total synthesis of pamamycin607 1 is described. The synthesis of the C(1)–C(18) fragment involved the tin(IV) chloride-promoted reaction between (3R)-3-(N-methyl)tosylaminohexanal 18 and the allylstannane 4 followed by cyclisation and reductive removal of the phenylselanyl group to give the tetrahydrofuran 20 which was taken through to the aldehyde 21. Aldol addition of the lithium enolate derived
