Pyrrolo[2,3-d]thiazoles are conveniently derived from the corresponding o-aminoalkynylthiazoles via microwave assisted 5-endo-dig cyclization. Methylene-bridged substituents in the 6-position are directly obtained from 5-exo-Heck cyclization based on the same iodoaminothiazole precursor. Further structural variety is accessible via Suzuki reaction of 2-chloroaminothiazoles prior to cyclization or post-cyclization
吡咯并[2,3- d ]噻唑方便地从相应的衍生ø辅助5- -aminoalkynylthiazoles经由微波内切-Dig 环化。基于相同的碘氨基噻唑前体,从5- exo- Heck环化反应中直接获得6-位的亚甲基桥接取代基。在环化或环化后修饰之前,可以通过2-氯氨基噻唑的Suzuki反应获得更多的结构变异。 噻唑-吡咯-杂环-微波辐射
