✦ Synopsis

Preparation of Novel Tricyclic Diazo Carbapenems: Application of Inverse Electron Demand Diels-Alder Reactions of 3,6-Bis(methylthio)- 1,2,4,-The construction of the novel tricyclic carbapenem precursor (VIII) (a single, unspecified diastereomer) is accomplished via the inverse electron demand Diels-Alder reaction of the alkynyl azetidinone (III) and the tetrazine (IV) and by intramolecular nucleophilic substitution of the diazine sulfone (VII). -(SAKYA,
