The N-protected β-aminonitriles 1 were transformed into the imidoester or thiolimidoester hydrochlorides 2 or 3 according to Pinner and sulfhydrolyzed with H2S to give the N-protected β-amino thiono esters 4 or dithio esters 5. Alkylation of th

Acylation of Dibasic Compounds Containing Amino Amidine and Aminoguanidine Functions

Barker, Peter L.,Gendler, Paul L.,Rapoport, Henry

, p. 2455 - 2465 (2007/10/02)

The site of acylation in difunctional compounds containing an amine and either an amidine or guanidine can be determined from the ultraviolet absorption spectrum of the acylated product.If the amidine or guanidine has been acylated, the product possesses a chromophore that is pH dependent, whereas if an amide was formed, the chromophore is independent of pH.
