Stereocontrolled synthesis of C10-C22 fragment of the immunosuppressant FK 506. An occurrence of complementary stereoselectivity in the C15 ketone reduction

The stereoselective syntheses of the C10-C22 fragment 2a and its C15-epimer 2b of the immunosuppressant FK 506 1 have been carried out through convergent coupling of the sulfone 3, which could be constructed by highly stereocontrolled ester-enolate Claise

A Synthesis of C1-C22 Fragment of the Immunosuppressant FK 506. Stereoselective Construction of (E)-Trisubstituted Double Bond (C19-C20) via Ester-enolate Claisen Rearrangement

An ene-ester 5 prepared from L-malic acid was subjected to the ester-enolate Claisen rearrangement under Ireland's condition to give stereoselectively C16-C22 fragment 11 containing (E)-trisubstituted double bond which was further advanced to C1-C22 fragm
