Sharma, Richa;Yadav, Lalit;Yadav, Ravi Kant;Chaudhary, Sandeep research published 《 Oxidative cross-dehydrogenative coupling (CDC) via C(SP2)-H bond functionalization: tert-butyl peroxybenzoate (TBPB)-promoted regioselective direct C-3 acylation/benzoylation of 2H-indazoles with aldehydes/benzyl alcohols/styrenes》, the research content is summarized as follows. An efficient, cost-effective, transition-metal-free, oxidative C(SP2)-H/C(SP2)-H cross-dehydrogenative coupling via a C(SP2)-H bond functionalization protocol for the regioselective direct C-3 acylation/benzoylation of substituted 2H-Indazoles I (R = H, F, Cl, OMe; R1 = H, Me; RR1 = -OCH1O-; R2 = H, Cl, Me, OMe; X = CH, N) with substituted aldehydes R3CHO (R3 = Me, Ph, pyrrol-2-yl, etc;)/benzyl alcs. R3CH2OH/styrenes R3CH=CH2 is reported. The operationally simple protocol proceeds in the presence of tert-Bu peroxybenzoate (TBPB) as an oxidant in chlorobenzene (PhCl) as a solvent at 110°C for 24 h under an inert atm., which furnished a diverse variety of substituted 3-(acyl/benzoyl)-2H-indazoles II in up to 87% yields. The reaction involves a free-radical mechanism and proceeds via the addition of an in situ generated acyl radical (from aldehydes /benzyl alcs./styrenes) on 2H-indazoles. The functional group tolerance, broad substrate scope, control/competitive experiments and gram-scale synthesis and its application to the synthesis of anti-inflammatory agent III and novel indazole-fused diazepine IV further signify the versatile nature of the developed methodol.
