Ring Contracting Rearrangements of 3‐Amino‐4‐(arylamino)‐1 H ‐isochromen‐1‐ones

Two new ring contracting rearrangements of 3‐amino‐4‐(arylamino)‐1 H ‐isochromen‐1‐ones, leading to 1‐(arylamino)‐3‐oxo‐1,3‐dihydroisobenzofuran‐1‐carboxamides and2‐aryl‐3‐oxo‐2,3‐dihydro‐1 H ‐isoindole‐1‐carboxamides, are described. Both conversions proceed in high yield and no further purification...

Description
Summary:Two new ring contracting rearrangements of 3‐amino‐4‐(arylamino)‐1 H ‐isochromen‐1‐ones, leading to 1‐(arylamino)‐3‐oxo‐1,3‐dihydroisobenzofuran‐1‐carboxamides and2‐aryl‐3‐oxo‐2,3‐dihydro‐1 H ‐isoindole‐1‐carboxamides, are described. Both conversions proceed in high yield and no further purification of the products is necessary. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
