Esterification interne d'ω-hydroxyacides par action de Bu 2 SnO basee sur un processus «template». Application a la synthese de zearalenone, ingramycene, nodusmicine, pyrenophorine et vermiculine. Les β- et ω-aminoacides a longue chaine conduisent preferentiellement a des polymeres mais on arrive cependant a obtenir des lactames a 5, 6 et 7 chainons a partir des ω-aminoacides correspondants

A palladium catalyzed coupling reaction of an organotin reagent bearing acrylate functionality with an acidchloride serves as a method to introduce both a ketone and an acrylate functionality into a carbon framework; thus the coupling reaction of 4-t-butyldiphenylsiloxypentanoyl chloride with benzyl 3-tributylstannylacrylate gave a 71% yield of benzyl 7-t-butyldiphenylsiloxy-4-oxo-2-octenoate, which
