The regioselective palladium catalysed hydrostannylation of alkynes bearing
a beta-heteroatom affords mainly alpha-vinyltin(IV) compounds that are use
d as terminating species in palladium catalysed cyclisation-anion capture p
rocesses. The pharmacophore attached to the alkyne moiety permits the synth
esis of sugars, nucleosides, purines, benzodiazepinones and beta-lactams an
alogues in good yields. (C) 2000 Elsevier Science Ltd. All rights reserved.
