Substituted chrysenes have been swiftly synthesised by the 6-endo-dig cyclisation of ethynylnaphthalenes using platinum(II) chloride. Cyclisation precursors were directly prepared from commercially available 2-bromoaldehydes in a telescoped synthetic procedure involving a Cannizzaro triggered cascade and subsequent dehydration and desilylation. This short synthetic procedure allows rapid access to
通过使用氯化铂(II)对乙炔基萘进行6-内挖-环化反应,已快速合成了取代的chrysenes 。环化前体是由可商购获得的2-溴醛直接制备的,其合成过程涉及Cannizzaro触发级联反应以及随后的脱水和甲硅烷基化反应。这种短的合成程序可以快速获得具有有用电子特性的生物活性分子的衍生物。
