摘要：
A derivative of 6-aminopenicillanic acid or 7-aminocephalosporanic acid is produced by a process which comprises disulfidizing a 6-thioacylaminopenicillanic acid or 7-thioacylaminocephalosporanic acid compound to obtain a corresponding disulfide compound, and then solvolyzing the disulfide compound. The process is novel and industrially feasible for producing the amino compound, which is not accompanied by "reconversion reaction".
