Abstract

1527110 2-Thienylsulphinylacetic acid ASAHI KASEI KOGYO KK 22 Dec 1975 [28 Dec 1974 15 July 1975] 16494/78 Divided out of 1527109 Heading C2C 2-Thienylsulphinylacetic acid is obtained by oxidation of 2-thienylthioacetic acid with H 2 O. The starting material may be obtained from 2- mercaptothiophene and monochloroacetic acid. The isomer having positive optical rotation (α) D in ethanol is useful in the preparation of cephalosporin derivatives having lower minimum inhibiting concentration against Gramnegative bacteria c. f. the isomer with negative rotation.
