a-amino-stabilized radical
为什么阿尔法胺基可以稳定自由基
如题，也就是说下图的加成产物为什么是7而不是烷基加在阿尔法碳上？
哈哈是缩合吧

Synthesis of 2-pyrolyl-2-hydroxy-2-cyanoacetamide through FeCl3&TBHP mediated hydroxylation of captodative stabilized radical intermediate, ,
Department of Chemistry, University of Calcutta, 92, A. P. C. Road, Kolkata 700 009, IndiaA series of 2-hydroxy-2-(4-oxo-1,2-diaryl-4,5,6,7-tetrahydro-1H-3-indolyl)-2-cyanoacetamides have been synthesized through selective CH oxidation of active methylene carbon of cyanoacetamide derivatives using tert-butyl hydroperoxide as oxidant and ferric chloride as radical initiator. In this reaction the tert-butyl oxo radical abstracts hydrogen from the active methylene group of 2-pyrolyl-2-cyanoacetamides to generate a stable captodative radical intermediate. Then recombination of this radical intermediate with tert-butyl oxo radical followed by acid catalysed thermal elimination of the tert-butyl group produces the quaternary hydroxyl cyanoacetamide derivatives in good yield.KeywordsHydroxylation; TBHP&FeCl3; Radical pathway; 2-Hydroxy-2-cyanoacetamide; Captodative radicals

【化学活动周---有奖活动】有机化学专业导师巡礼
前一段时间看到有好多虫子为联系导师而发愁，仔细思考这确实是个问题，因为我们毕竟了解的很少。为此，在这07年即将离去，08年马上来临之际，我先代表有机版全体版主祝所有来有机板的虫子新年快乐，在新的一年里心想事成，一帆风顺！
现趁化学区活动周之际，他举行这次活动，希望大家积极参与！跟帖格式：
导师姓名：
研究方向：
所在单位：
硕导 or 博导：
导师简介：
研究成果：
单位科研实力：
（注：最好附上导师照片）必须按照以上格式跟帖，凡参与者奖获得3~5金币的奖励。
我要再次说明的是，请大家务必认真回帖，但活动结束后，我将整理资料做成电子书，这样将会方便很多新虫子，也为大家提供一个为自己导师宣传一下的平台，希望大家踊跃参与！
