1-Arylsulfonyl-3-(α-hydroxybenzyl)-1H-pyrroles, a novel class of anti-HIV-1 reverse transcriptase inhibitors
摘要:
Various 1-arylsulfonyl-3-(alpha-hydroxybenzyl)-1H-pyrroles were prepared by Friedel-Crafts reaction of 1-aryisulfonyl-1H-pyrroles with aroylchlorides in the presence of aluminum trichloride, followed by reduction of the ketones to the required carbinols. Title compounds were identified as a novel class of nonnucleoside HIV-1 reverse transcriptase inhibitors characterized by the presence of a diarylcarbinol moiety, a chemical feature that strictly correlates with the anti-HTV-1 activity.

C–H bonds has become a dominant research theme in the past decade as an approach to efficient synthesis. However, the incorporation of carbon monoxide into such reactions to form valuable ketones has to date proved a challenge, despite its potential as a straightforward and green alternative to Friedel–Craftsreactions. Here we describe a new approach to palladium-catalysed C–H bond functionalization

three components including 2,2-dimethoxyethylamine, aryl/alkyl sulfonyl chlorides and alkynes bearing electron-withdrawing groups is presented. The pyrroles are proposed to arise via a 5-exo-trig cyclization proceeding through both oxocarbenium and N-sulfonyliminium ions. This modular route allows for the variability at the N-sulfonyl group, the C2 and C3 substituents for rational vectoring of the pyrrole
介绍了从 2,2-二甲氧基乙胺、芳基/烷基磺酰氯和带有吸电子基团的炔烃等三种组分构建吡咯的三步序列。吡咯被认为是通过氧碳鎓和N-磺酰亚胺离子进行的5- exo -trig 环化产生的。这种模块化路线允许N-磺酰基、 C 2 和 C3 取代基的可变性,以便为下游过程的吡咯核进行合理矢量化。
