Abstract

(3) PNB is equivalent to p-nitrobenzyl.(4) The numbering of the ring system adopted throughout this and the previous paper is based on assignment of the terms carbapenam, carbapen-1-em, and carbapen-2-em to structures a, b. and c, respectively. This nomenclature is analogous to the penam and cepham nomenclature currently employed in p-lactam chemistry.
