Reduction of 2,4-diacylpyrroles followed by dehydration to prepare the divinylpyrroles has been studied. The N-phenylsulfonyl group exhibited directing ability at the 4-position during the reduction of 2,4-diacylpyrrole and complete regioselectivity was achieved for formations of the 2- and 4-carbinols; several new derivatives, including 2,4-divinylpyrrole, have been prepared.(© Wiley-VCH Verlag GmbH
已经研究了 2,4-二酰基吡咯的还原,然后脱水以制备二乙烯基吡咯。N-苯基磺酰基在2,4-二酰基吡咯的还原过程中在4-位表现出导向能力,并且对2-和4-甲醇的形成实现了完全的区域选择性;已经制备了几种新的衍生物,包括 2,4-二乙烯基吡咯。(© Wiley-VCH Verlag GmbH & Co. KGaA,69451 Weinheim,德国,2009)
