coupling of triorganoindiumreagents with benzopyranyl acetals mediated by a Lewis acid has been developed. The reaction of R3In with chromene and isochroman acetals in the presence of BF3·OEt2 afforded 2-substituted chromenes and 1-substituted isochromans, respectively, in good yields. The reactions proceed with a variety of triorganoindiumreagents (aryl, heteroaryl, alkynyl, alkenyl, alkyl) using

[Au]-catalyzed [3 + 3] cycloaddition reaction of enynones/enynals with azides, which allows the efficient regioselective synthesis of highly fused furo[3,4-d][1,2,3]triazines in good-to-excellent yields under mild conditions, has been developed. The syntheticutility of furanotriazines was exploited by oxidation with cerium ammonium nitrate (CAN) affording highly functionalized dihydrotriazines. Both
乙炔/烯醛与叠氮化物的[Au]催化的[3 + 3]环加成反应,可在良好或优异的条件下有效地选择性合成高度熔融的呋喃[3,4- d ] [1,2,3]三嗪已经开发了在温和条件下的产量。通过用硝酸铈铵(CAN)氧化来开发呋喃三嗪的合成效用,从而提供高度官能化的二氢三嗪。呋喃[3,4- d ] [1,2,3]三嗪和二氢三嗪均显示出良好的荧光活性。
