New method for the synthesis of pyrromethanes

Coupling reaction of 2-mercaptobenzothiazolylmethylpyrrole with α-free pyrrole in the presence of silver(I) triflate proceeds smoothly at room temperature to give a pyrromethane in excellent yield. The azafulvenium ion, an active form that reacts with α-f

2-Mercaptobenzothiazolylmethylpyrrole as a new means for the synthesis of pyrromethanes under neutral conditions

The coupling reaction of 2-mercaptobenzothiazolylmethylpyrrole 4b with α-free pyrrole 2b in the presence of silver (I) triflate proceeds smoothly at room temperature to give pyrromethane 1b in excellent yield. 4b reacts rapidly with pyrromethane 1b under

SYNTHESIS OF UROPORPHYRIN-III, AND RELATED HEPTA- AND PENTA-CARBOXYLIC PORPHYRINS BY MODIFICATIONS OF THE MACDONALD METHOD

A modification of the MacDonald route has been developed in which all four pyrrole units of uroporphyrin-III have been derived from the same conveniently prepared starting pyrrole.Related hepta- and penta-carboxylic porphyrins have also been synthesised by condensation of appropriate α-formyl pyrromethane-α'-carboxylic acids; in each case other porphyrins with different numbers of acidic side-chains were also produced but the desired products were easily separated (as their methyl esters) by h.p.l.c.
