摘要

Title cpds. are of formula (I): where A = -YCO2H or -CON(R1)YCO2H; Y = 1-4C alkylene; Z = single bond or -CH2CH2-; and R and R1 = H, 1-4C alkyl opt. substd. by OH or alkoxy, 2-4C alkenyl, cyclohexyl, Ph or PhCH2; and include esters and salts of (I). (I) are prepd. by a) condensing a 1-A-3-amino-2,4,6-tri-iodobenzene with a pyrrolidine or caprolactam deriv. and POCl3, or b) prepg. similarly, analogues with A = COCl, and subsequently condensing with HN(R1)YCO2-Alkyl
