Tin(IV)-catalyzed lactonization of ω-Hydroxy trifluoroethyl esters
摘要:
1,1,1-Trifluoroethyl esters of omega-hydroxycarboxylic acids were prepared and their conversion to macrocyclic lactones, including ricinelaidic lactone, was studied in the presence of catalytic quantities of tin(IV) reagents; a mechanism involving exchange of alkoxytrialkyltin species is proposed.
