ABSTRACT:
The invention relates to the 3-(1'-hydroxyethyl)-2-azetidinone of formula ##STR1## which can be transformed into 4-acyloxy-3-(1-hydroxyethyl)-2-azetidinone derivatives. The latter can be used as starting materials for the manufacture of a large number of highly active .beta.-lactam antibiotics.
