Rhodium(II)-Catalysed Skeletal Rearrangement of Ether Tethered<i>N</i>-Sulfonyl 1,2,3-Triazoles: a Rapid Approach to 2-Aminoindanone and Dihydroisoquinoline Derivatives
The skeletalrearrangement of ether tethered N‐sulfonyl‐1,2,3‐triazoles has been achieved by rhodium(II) catalysis. This method offers a rapid entry to 2‐aminoindanone and dihydroisoquinoline architectures which can be further transformed to other valuable building blocks, such as vicinal aminoindanols, isoquinolines and isoquinolinones. A pathway involving an azavinyl rhodium carbene intermediate
