3-b]pyrrol-6-amines from readily accessible starting materials (propargylamines, isothiocyanates, and propargyl bromide) has been developed. The methodology is based on the one-pot synthesis and thermally-induced fast rearrangement of 5-(prop-2-ynylsulfanyl)-1H-pyrrol-2-amines into 2,7-dihydrothiopyrano[2,3-b]pyrrol-6-amines. An expedient approach for the preparation of previously unknown 2,7-dihydrothiopyrano[2
摘要 已经开发了一种从容易获得的起始原料(炔丙基胺,异硫氰酸酯和炔丙基溴)中制备未知的2,7-二氢硫代吡喃并[2,3- b ]吡咯-6-胺的简便方法。该方法基于一锅合成和热诱导的5-(丙-2-炔基硫烷基)-1 H-吡咯-2-胺快速重排为2,7-二氢噻喃并[2,3- b ]吡咯- 6胺 已经开发了一种从容易获得的起始原料(炔丙基胺,异硫氰酸酯和炔丙基溴)中制备未知的2,7-二氢硫代吡喃并[2,3- b ]吡咯-6-胺的简便方法。该方法基于一锅合成和热诱导的5-(丙-2-炔基硫烷基)-1 H-吡咯-2-胺快速重排为2,7-二氢噻喃并[2,3- b ]吡咯- 6胺
