A process for producing a beta-lactam compound of the general formula
wherein R represents a hydrogen atom or a methyl group, R2 represents a hydrogen atom, a hydroxyl group which may be protected or a hydroxymethyl group which may be protected, R3 represents a hydrogen atom, or together with R1 forms a single bond, Rs represents an ester residue and R6 represents a hydrogen atom or a monovalent organic group, which comprises reacting a compound of the general formula
wherein R1, R2, R3 and R5 are as defined above, R4 represents -CH2-CH2- or -CH=CH-, and Y represents a protected amino group, with a thiol compound of the formula
or its reactive derivative; and noble intermediate useful for the above process.
