Nucleophilic substitution reactions of racemic and chiral 5-acetoxy-, 5-ethoxy-, and 5-methoxypyrrolidin-2-ones by silicon-based nucleophiles were efficiently catalyzed by TIPSOTf. This process was found to be general and accommodates a broad range of substrate-nucleophile combinations.

Herein we have reported design, synthesis and in vitro biological evaluation of a library of bicyclic lactams that led to the discovery of compounds 6 and 7 as a novel class of α-glucosidase inhibitors. They inhibited α−glucosidase (yeast origin) in a mixed type of inhibition with an IC50 of ∼150 nM. Molecular docking studies further substantiated screening results. Interestingly phenotypic screening
