摘要:
Certain vinyl acetylene benzimidazole compounds which inhibit the growth of picornaviruses, such as rhinoviruses, enteroviruses, cardioviruses, polioviruses, coxsackieviruses of the A and B groups, echo virus and Mengo virus.
摘要:
Imino chlorides of 6-aminopenicillanic esters and 7-aminocephalosporanic esters are reacted at a temperature between -80.degree. and -25.degree. C. with a strong base such as an alkali metal amide of a secondary amine and the generated anion is halogenated to provide the corresponding 6- or 7-halo-N(.alpha.-haloalkylidene) or N(.alpha.-halo-.alpha.-arylmethylidene)-6-aminopenicillanic or 7-aminocephalosporanic esters, respectively. The 6-halopenicillins and 7-halocephalosporins are converted to 6-methoxypenicillins and 7-methoxycephalosporins.
