Abstract

NEW MATERIAL:A compound of formula I (R1 is amino, protected amino, or arylacetamido; R2 is lower alkyl).
EXAMPLE: Methyl 4,5,8,8a-tetrahydro-7-oxo-8-phthalimido-7H-azeto[1,2-a]-thieno [2,3-c]pyridine-5-carboxylate.
USE: Antibacterial agent effective to gram-positive and gram-negative bacteria. Intermediate for the synthesis of pharmaceuticals.
PROCESS: A compound of formula I wherein R1 is R3 (the compound of formula I') is prepared by reacting a compound of formula II with a compound of formula III (R3 is protected amino), e.g. phthaloylglycyl chloride, in a solvent such as benzene, in the presence of a base or an acid acceptor (e.g. triethylamine).
