(Chemical Equation Presented) The 2-trimethylsilylethanesulfonyl (or SES) protecting group was compared to the tosyl (Ts) group in the preparation of a nitrogen-containing five-membered ring obtained by the aza-Baylis - Hillman/alkylation/RCM route. While

A new route to diverse 2-substituted-3-methoxycarbonyl pyrroles has been developed. Diverse SES protected α-methylene β-aminoesters were obtained by a 3-component aza-Baylis-Hillman reaction. Diversity arose from the aryl aldehydes which can be used in th
