A novel method for the synthesis of fused pyrimido[1,6- a ]-indolone derivatives by annulation of 2-alkynylaryl aldehydes/2-alkynyl arylidene ketones with N -(pivaloyloxy)-1 H -indole-1-carboxamide catalyzed by rhodium has been accomplished. The reaction proceeds through C-H activation based annulation with alkyne moiety followed by addition of nitrogen on to aldehyde/activated alkene to give the products in moderate to good yields. Highly fluorescent dipyrrinone analogues could be synthesized from the derived products.

In this work, a rhodium-catalyzed oxidative cycloaromatization of dienynes, which provides a highly straightforward and efficient way to access polysubstituted naphthols and phenols under mild conditions, is described. Challenged electron-withdrawing groups are well tolerated in this protocol, and late-stage phenyl ring formation is demonstrated.
