  Tandem Migration–Carboalkoxylation of o-Isocyanophenyl Acetals Leading to Benzoxazoles

  摘要：

  An efficient approach to benzoxazoles via tandem migration carboalkoxylation of o-isocyanophenyl acetals has been developed. Both a Lewis acid and base are essential for this reaction, and the BF3 center dot OEt2/2,4,6-collidine combination is the best choice for cooperative transformation.

  metal-free novel, simple, and highly efficient method for the direct C2-alkylation of azoles with alcohols and ethers has been developed on the basis of an oxidative C–H activation process. The dehydrogenative C–C cross-coupling reactions of α-position sp3 C–H in alcohols and ethers with the 2-position sp2 C–H in azoles proceeded smoothly in the presence of tert-butyl hydroperoxide (TBHP) under neat reaction

  在氧化CH活化过程的基础上，开发了一种无金属的新颖，简单，高效的方法，用于将唑类与醇和醚直接进行C2-烷基化反应。在叔丁基过氧化氢（TBHP）存在下，在纯净反应下，醇和醚中的α-位置sp 3 C-H与唑类中的2-位sp 2 C-H的脱氢CC交叉偶联反应顺利进行条件下，产生相应产物的收率很高。

  The direct 2-alkylation of oxazoles and thiazoles with ethers through cross-dehydrogenative coupling reaction using Co-containing mesoporous zeolite ETS-10 as the heterogeneous catalyst is described. The basic Co-containing mesoporous zeolite ETS-10 catalyst facilitates this cross-dehydrogenative coupling reaction through metal-base synergy catalytic principle.

  The cobalt-catalyzed cross-dehydrogenative coupling of (benz)oxazoles and ethers is described. Access to some important bioactive heteroaryl ether derivatives was achieved using CoCO3 as an inexpensive catalyst at levels as low as 1.0 mol %. Investigation of the mechanism indicates a catalytic cycle involving a radical process.
