2-Heterocyclyl-lower alkyl-6-hydroxy-lower alkyl-2-penem compounds of the formula ##STR1## in which R.sub.1 represents lower alkyl substituted by hydroxy or protected hydroxy, R.sub.2 represents carboxy or functionally modified carboxy, R.sub.3 represents an unsaturated monocyclic azaheterocyclyl radical bonded via a tertiary ring nitrogen atom to the radical -A- and A represents a lower alkylene radical, optical isomers of compounds of the formula (I), mixtures of these optical isomers and salts of such compounds of the formula (I) that contain a salt-forming group have antibiotic properties. The novel compounds can be used, for example, in the form of antibiotically active preparations for the treatment of infectious diseases. The novel compounds can be manufactured in a manner known per se.
