In a document, author is Rees, CW, introducing its new discovery. Name: 4-(Methylamino)benzoic acid.
The reaction of 2,5-diarylfurans with trithiazyl trichloride 1 to give 5-aroyl-3-arylisothiazoles in a useful one-step synthesis of isothiazoles has been extended to both weakly and strongly polarised unsymmetrical 2,5-diarylfurans, These react in an entirely analogous manner; the more electron releasing aryl group becomes incorporated into the 5-aroyl group of the isothiazole as the exclusive (strong polarisation) or the major (weak polarisation) product, However, with 3-bromo-2-(4-methoxyphenyl)-5-(4-nitrophenyl)-furan 7, where the more reactive furan beta-position is now substituted, this regiospecificity is reversed (to give isothiazole 8), When one of the alpha-aryl groups in the furan is replaced by methyl the same regiospecific isothiazole formation is now accompanied by some ring and side chain chlorination (15–>16 + 17 + 18), All of these results can be explained by mechanisms (Schemes 2 and 5) which involve initial electrophilic attack of the furan to give a beta-thiazyl derivative, This highly reactive (nitrenoid) substituent then induces a novel opening of the furan ring 21 to give a highly delocalised intermediate 22 which recyclises to the isothiazole.
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 10541-83-0. Name: 4-(Methylamino)benzoic acid.
