amino acid radicals. Optimized structures of glycine derivatives and related substituted methanes, and the corresponding radicals, were determined with B3-LYP/6-31G(d). Single-point RMP2/6-31G(d) calculations on these structures were then used to obtain radical stabilization energies, which were compared with the relative rates of formation of the same or closely similar radicals in reactions with N-bromosuccinimde

dithioacyl papain fits the rate-structure correlation whereas the corresponding pentafluorobenzoyl glycine thiol intermediate does not. It is proposed that the difference in the size of the CS compared to the CO group brings about a small change in the dithioacyl papain compared to the thiolacyl papainconformation such that enzyme-substrate contacts involving ortho and meta F atoms in the thiol acyl enzyme

N-alkyl-3-methenyl chiral isoindolinone derivatives from aryl amides of L-amino acids and non-activated alkene via Pd-catalyzed C(sp2)–H olefination. Herein, the aminoacid residue acts as a directing group for olefination at the aryl ring, and then cyclization occurs at the amide NH. Hence, this methodology could be helpful to transform standard aminoacids into respective chiral isoindolinone derivatives.
