lost; these compounds also inactivated cytochromeP-450 and caused the loss of nifedipine oxidase activity after enzymaticoxidation. All of these reactions were extensively inhibited by an antibody raised to purified human liver nifedipine oxidase cytochromeP-450 (P-450NF), indicating a major role for this enzyme in the oxidation of these compounds. Oxidation of the 4-alkyl compounds led not only

vital transformation for the development of pharmaceuticals, functional materials, and other chemical entities. Herein, the transition-metal-free alkylation and acylation of C(sp2)–H bonds in biologically relevant 2-benzoxazinones with 1,4-dihydropyridines as readily accessible radical surrogates is described. Excellent functional group compatibility and a broad substrate scope were attained. Gram-scale
