Catalytic amounts of Pd(OAc)2 in the presence of -Bu4NCl, DMF and an appropriate base (Na2CO3, (NaOAc or Et3N) cyclize nitrogen-containing -iodoaryl alkenes to indoles, indolines,3 oxindoles, quinolines, isoquinolines and isoquinolones in short reaction times, under mild temperatures, and in high yields.
在-Bu 4 NCl,DMF和适当的碱(Na 2 CO 3,(NaOAc或Et 3 N)存在下,催化量的Pd(OAc)2可以将含氮的碘代芳基烯烃环化成吲哚,二氢吲哚,3氧吲哚,喹啉,异喹啉和异喹诺酮在较短的反应时间内,在温和的温度下,收率很高。
Cathodic reduction of N-(2-iodophenyl)-N-alkylcinnamides: a novel sequential electrochemical radical cyclisation and hydroxylation
cyclisation has emerged as a useful route for the synthesis of benzannulated heterocycles and carbocycles. The aryl radicals are generated in situ from aryl halides (iodides or bromides) with tributylstannyl hydride–AIBN, SmI2, Co(I) or under photochemical conditions. The present work envisages the generation of aryl radicals by cathodic reduction of the carbon–iodine bond of N-(2-iodophenyl)-N-alkylcinnamides
