Preparation of sulfonamide derivatives as metal chelators

Preparation of sulfonamide derivatives as metal chelators. Okada, Hisashi; Yagihara, Morio (Fuji Photo Film Co.Except for chemicals metioned above, 21896-59-3 is also used., Ltd., Japan). Ger. Offen. DE 4142960 A1 2 Jul 1992, 9 pp. (Germany). CODEN: GWXXBX. CLASS: ICM: C07C311-05. ICA: G03C005-30; G01N031-16. APPLICATION: DE 91-4142960 24 Dec 1991. PRIORITY: JP 90-405649 25 Dec 1990.In this experiment, several chemicals are used like 21896-59-3 DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) Section cross-reference(s): 54 Sulfonamide derivs. RSO2NHZ1NXY (R = alkyl, XZ2CO2M, WNZZ1HSO2R; Y = RSO2NHZ1, Z2CO2M; Z1, Z2 = alkylene; Z = Y; M = H, cation; X and Y are not simultaneously = Z2CO2M] were prepd. as metal chelators (no data). Thus, 0.42 mol ClCH2CH2NHSO2Me and 0.42 mol 5N NaOH were added to a soln. of 0.20 mol glycine in 0.20 mol 5N NaOH at 50°. The soln. was stirred 5 h at 50 to give (MeSO2NHCH2CH2)2NCH2CO2H in 32% yield. ..
