With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4570-41-6,Benzo[d]oxazol-2-amine,as a common compound, the synthetic route is as follows.,4570-41-6
Amide-containing compounds with (benz)imidazol-2-yl groups can undergo catalytic directed cleavage with an alcohol nucleophile 11 in the presence of a metal catalyst. The following examples as depicted in Example Scheme ES can be listed:_Using 15.0 molpercent Zn(OAc)2.17H20, 1.0 equiv 9a, 6.0 equiv 16, tBuOAc, 100 ¡ãC, 48 h.1,3-bis(Benzo[d]oxazol-2-yl)urea (18a) was obtained in 59percent (0.087 g, 0.296 mmol) yield. White crystals ; m.p. 130 ¡ãC. 13C-NMR (100 MHz, DMSO-d6): : 162.7 (Cquat), 147.8 (Cquat), 143.4 (Cquat),123.4 (CH), 119.9 (CH), 115.3 (CH), 108.3 (CH).
4570-41-6 Benzo[d]oxazol-2-amine 20707, abenzoxazole compound, is more and more widely used in various fields.
