J. Thibonnet et al., TRIBUTYLSTANNYL 4-TRIBUTYLSTANNYLBUT-3-ENOATE - A USEFUL C-4 HOMOLOGATING AGENT - APPLICATION TO THE SYNTHESIS OF ARYL IODOLACTONES, Tetrahedron letters, 37(42), 1996, pp. 7507-7510
Tributylstannyl 4-tributylstannylbut-3-enoate, readily prepared by rad
ical hydrostannation, is used for the transfer of a but-3-enoic acid s
ynthon. Some of the potentialities of this synthon are established by
the synthesis of aryl iodolactones or tetralones (one of them is a key
intermediate for ABT-200 synthesis). Copyright (C) 1996 Published by
