The AlCl3-promoted reactions of cycloalkanones with hydrazones are described. This approach represents a mild and operationally simple method to access 2,3-diaryl-4,5,6,7-tetrahydro-1H-indazoles and their analogues in good to moderate yields.

The authors regret that the printed version of the above article contained errors in Tables 1 and 2. A plausible mechanism was proposed using 1-benzylidene-2-phenylhydrazine 1a and cyclohexanone 2a as model reactants (Scheme 2). The formation of aluminum

In order to control the regiochemistry of the cycloaddition of diphenylnitrilimine on 1,2-dihydronaphtalene and at-1 or -2 substituted derivatives and to obtain either regioisomer, we introduce a methoxycarbonyl group at the 4- or 3- position of the dipol

Diphenylnitrilimine cycloaddition reactions on 1,2-dihydronaphtalenes are only regioselective.Use of 1- or 2-tetralones enamines as dipolarophiles allows to attain regiospecificity.
