A series of derivatives of 1-(4-octylphenoxy)-3-(2H-tetrazol-2-yl)propan-2-one (3) and 1-(4-octylphenoxy)-3-(1H-tetrazol-1-yl)propan-2-one (4) was synthesized and tested for fatty acidamide hydrolase (FAAH) inhibitory potency and phase I metabolic stability. Introduction of certain substituents like 4-chlorophenyl, 4-methoxycarbonylphenyl and carboxyl in position 5 of the tetrazole ring of 3 led to

We report a modular three-component dynamic kinetic resolution (DKR) that affords enantiomerically enriched hemiaminal esters derivedfrom azoles and aldehydes. The novel and scalable reaction can be used to synthesize valuable substituted azoles in a regioselective manner by capping (e.g., acylation) of the equilibrating azole-aldehyde adduct. With the use of a prolinol-derived DMAP catalyst as the
