One-Pot Synthesis of Benz[f]Indolo[3,2-c]isochromeno- 5,7,13-trione Derivatives from 2-Amino-1,4-naphtho-quinones and Ninhydrin
摘要:
An efficient method for the preparation of novel benz[f]indolo[3,2-c]isochromeno-5,7,13-triones 3 was described. The construction of this new pentacyclic system was achieved undergo a domino reaction of 2-amino-1,4-naphthoquinones 1 with ninhydrin 2 in one-pot with good yields.
报道了第一个 Fe 催化的烯烃与 2-氨基-1,4-萘醌和 CF 3 SO 2 Na 的三组分自由基三氟甲基烯基化反应。所开发的反应能够以可接受的收率高度区域选择性地制备各种有价值的 CF 3 -取代的 1,4-萘醌。根据催化体系,炔烃可以顺利地提供相应的三或四组分三氟甲基-烯基化产物。该协议的特点是使用容易获得且价格低廉的试剂、广泛的底物范围和简单的反应条件。

The manganese(III) initiatedoxidativefreeradicalreactionbetween 1,4-naphthoquinones and ethyl nitroacetate is described. Nitromethyl radical 1 can be generated effectively from the oxidation of ethyl nitroacetate by manganese(III) acetate. Naphtho[2,3-d]isoxazole-4,9-diones, benzo[f]indole-4,9-diones and benzo[b]acridine-6,11-diones were prepared effectively from readily available 1,4-naphthoquinones
描述了锰(III)引发的1,4-萘醌与硝基乙酸乙酯之间的氧化自由基反应。硝基甲基自由基1可以有效地从硝基乙酸乙酯的由乙酸锰氧化而产生。从容易获得的1,4-萘醌有效地制备萘并[2,3 - d ]异恶唑-4,9-二酮,苯并[ f ]吲哚-4,9-二酮和苯并[ b ] ac啶-6,11-二酮和硝基乙酸乙酯。
