-
Paragraph 0027; 0030; 0031, (2020/03/12)
The invention discloses a penicillin G sulfoxide diphenyl methyl ester synthesis method, which comprises: esterifying a penicillin G potassium salt as an initial raw material, and oxidizing through 2KHSO5.KHSO4.K2SO4 to synthesize the penicillin G sulfoxi
CONCERNING THE INTERMEDIACY OF MONOCYCLIC β-LACTAMS IN PENICILLIN BIOSYNTHESIS: SYNTHESIS AND ATTEMPTED BIOCONVERSION OF SECO-ISOPENICILLIN N

, p. 909 - 927 (2007/10/02)
The title compound (3a) was synthesized as its dimer by the skeletal rearrangement of protected isopenicillin N-sulfoxide, hydrogenation, hydrolysis of the thiazoline ring, oxidative dimerization and deprotection.The reductive conversion of the dimer to m

Cyanuric chloride reacted with 3-molar equivalents of pyridine to give 2,4,6-tripyridinio-1,3,5-triazine trichloride, which was found to condense penicilins with alcohols under mild conditions to afford penicillin esters in good yields.Application to prep
Oxidation Studies on β-Lactam Antibiotics. The 6-(Diacylamino)penicillins
Micetich, Ronald G.,Singh, Rajeshwar,Shaw, Chia C.
, p. 1811 - 1815 (2007/10/02)
The oxidation of the 6-(diacylamino)penicillins is a convenient, high yield route to the penicillin 1α-sulfoxides.The yield of the 1α-sulfoxide is dependent on the solvent, the temperature, the C-3 ester function, and the substituent at the C-2 position.T
Process for the preparation of esters of N-blocked penicillin acids which comprises reacting the acid or a salt thereof with a primary amine and a nitrosating agent

, (2008/06/13)
A process is described for the preparation of esters of N-blocked amino acids (such as penicillins or cephalosporins) wherein the amino acid or a salt thereof is reacted with a primary amine and nitrosating agent.
