A NEW AND EFFECTIVE AMINOMETHYLATION BY THE USE OF N-(p-TOLUENESULFONYLMETHYL)-p-TOLUENESULFONAMIDE AS AN EQUIVALENT OF METHANIMINE. A CONVENIENT PREPARATION OF PYRROLE COMPOUNDS

, p. 1033 - 1036 (2007/10/02)

Readily available N-(p-toluenesulfonylmethyl)-p-toluenesulfonamide was treated with base to generate N-methylene-p-toluenesulfonamide which reacted with a variety of nucleophiles forming the corresponding N-tosyl-aminomethylated compounds in good yields.Furthermore, the N-tosyl-aminomethylated acetals thus obtained were converted into the corresponding N-tosylpyrroles with the aid of acid catalyst in excellent yields.
