Preparation and reactivity of metalated (silicon and tin) thiazoles and oxazoles with carbon electrophiles. New approaches towards heterocyclic and acyclic building blocks

Thiazoles and oxazoles are transformed by C-silylation and C-stannylation into stable synthetic equivalents of thiazolyl and oxazolyl donor synthons wich upon regio- and chemoselective reactions with C-electrophiles provide new and wide-scope entries to functionally-substituted derivatives of these heterocycles
