(Richarson-Merrell Inc., USA). U.S. US 3994874 30 Nov 1976, 9 pp. Division of U.S.In this article, certain chemicals are used. Some of their cas registry numbers are 3279-76-3 and 30246-33-4 3,956,287. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07D499-58. NCL: 260239000. APPLICATION: US 73-413566 7 Nov 1973. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Penicillins I (R = H, 5-Cl, 3-OMe, 5-NH2) were prepd. by acylating 6-aminopenicillanic acid trimethylsilyl deriv. with pyridoneacetic acids prepd. by treating 2-pyridinols with BrCH2CO2Et in the presence of base. The cephalosporins II (R1 = OAc, 5-methyl-1,3,4-thiadiazol-2-ylthio) were similarly prepd. .
