1,3-Dipolar cycloaddition of arynes with azomethine imines: synthesis of 1,2-dihydropyrazolo[1,2-a]indazol-3(9H)-ones
摘要:
A [3+2] 1,3-dipolar cycloaddition reaction of arynes with stable azomethine imines has been developed. The reaction rapidly assembles tricyclic pyrazoloindazolone derivatives in moderate yields under mild reaction conditions. (C) 2009 Elsevier Ltd. All rights reserved.

Put it on a ring: A rhodium(III) complex can catalyze the oxidative coupling of azomethine imines with olefins, leading to the synthesis of 1,2‐dihydrophthalazines, olefinated aldehydes, or fused pyridines, depending on the conditions used.
