ABSTRACT:
There is presented optically uniform .beta.-lactams of the formulae ##STR1## wherein Z is a readily cleavable acyl group, R.sup.1 is amino or a group convertible into amino, R.sup.2 is hydrogen or a readily cleavable protecting group and R.sup.3 and R.sup.4 each are a lower hydrocarbon group which optionally contains oxygen and which is attached via a carbon atom, whereby these groups can also be joined with one another to form a ring, with the proviso that R.sup.1 is a readily cleavable acylamino when R.sup.2 is hydrogen,
and the corresponding optical antipodes, their manufacture and use in the manufacture of antimicrobially-active .beta.-lactams as well as novel intermediates usable in their manufacture.
