Zhang, Xueguo; Wang, Peigen; Zhu, Liangwei; Chen, Baohua published the artcile< Rhodium(III)-catalyzed chemodivergent annulations between phenyloxazoles and diazos via C-H activation>, Application of C11H12O3, the main research area is isocoumarin preparation regioselective chemoselective; isoquinolinone preparation regioselective chemoselective; diazo compound phenyloxazole carboxylic acid cyclization rhodium catalyst.
Acid-controlled, chemodivergent and redox-neutral annulations for the synthesis of isocoumarins I (R = t-Bu, 4-bromophenyl, cyclohexyl, thiophen-2-yl, etc.; R1 = Me, Et, Ph; R2 = Me, Et, t-Bu) and isoquinolinones II (R3 = t-Bu, heptyl, furan-2-yl, etc.) have been realized via Rh(III)-catalyzed C-H activation. Diazo compounds R1C(O)C(=N2)C(O)OR2 act as a carbene precursor, and coupling occurs in one-pot process, where adipic acid and trimethylacetic acid promote chemodivergent cyclizations.
