l-Proline catalyzed facile and efficient synthesis of functionalized indol-3-yl pyran derivatives by multi-component reactions
A simple and green synthetic method for preparation of functionalized indol-3-yl pyran derivatives was developed. The reactions were carried out by one-pot three-component synthesis of 3-cyanoacetyl indoles, malononitrile/cyanoacetate and various aldehydes/isatins/acenaphthenequinone in the presence of catalytic amount of l-proline. The advantages of this method included straightforward processing

A new synthesis of 5-hydroxy-benzo[a]carbazoles has been achieved by employing the photoinduced intramolecular C–H insertion of 2-aryl-3-(α-diazocarbonyl)indoles as the key step. This method is applicable to the synthesis of naturalproducts 6-cyano-5-methoxy-indolo[2,3-a]carbazoles 8 and 11 and their derivatives.
通过将光致分子内2-芳基-3-(α-重氮羰基)吲哚插入C-H分子内,已完成了5-羟基-苯并[ a ]咔唑的新合成。该方法适用于天然产物6-氰基-5-甲氧基-吲哚并[2,3- a ]咔唑8和11及其衍生物的合成。
