Abstract
The syntheses of novel tricyclic diazo carbapenem precursor 17, and th e deprotected carbapenems 2 and 3 are described. The construction of t he tricyclic carbapenem was accomplished by an intramolecular nucleoph ilic substitution of the diazine sulfone 16 which was obtained from an inverse electron demand Diels-Alder reaction of the alkynyl azetidino ne 13 with 3,6-bis(methylthio)-1,2,4,5-tetrazine (4).
