deprotonation susceptibility, such as tetramic and tetronic acids, cyclic 1,3-diketones, and cycloalkanones. Application to the synthesis of bioactive, pyrrolizine-fused 4-quinolinone, penicinotam 3, resulted in the most brief and highest yielding totalsynthesis of the alkaloid in three steps and a 36% overall yield.

Covalent, irreversible small-molecule inhibitors that modify the sulfenyl form (i.e., sulfenic acid, RSOH and sulfenamide, RSNR'2) of therapeutically important proteins (particularly kinases and phosphatases) are disclosed, where the compositions include a compound having a substituted aryl or heterocyclic core structure that promotes binding interactions with a specific protein, and a nucleophilic reaction center (carbon, nitrogen, sulfur, or phosphorous) that is capable of forming a covalent bond with a sulfenic acid- or sulfenamide-modified cysteine residue in the protein. Methods for synthesizing these compounds are also disclosed, as well as methods of using them for determining the bioactivity of a chemical composition comprising an active compound toward a specific protein and for determining the potency of an inhibitor against a specific protein.
