A new rearrangement of 1-(diarylmethyl)-2-isothiocyanatobenzenes into 2,4-diaryl-4H-3,1-benzothiazine derivatives is described. Treatment of the starting compounds with aluminum trichloride under Friedel-Crafts conditions leads to migration of an aryl sub

A simple route to 1-R-3-(2-indolyl)-1-propanones has been elaborated based on recyclization of 2-(2-aminobenzyl)furan derivatives. Being a modification of the Reissert indole synthesis, our approach employs the furan ring as a source of carbonyl function. This approach is general and allows varying of substituents in aromatic ring as well as in 3-position of indole nucleus.
