Microwave-Promoted Synthesis of Bicyclic Azocine-β-Lactams from Bis(allenes)
The Journal of Organic Chemistry, 2014 A metal-free preparation of structurally novel bicyclic azocine-β-lactams has been developed. The first examples accounting for the preparation of eight-membered rings from bis(allenes) in the absence of metals have been achieved by the thermolysis of nonconjugated 2-azetidinone-tethered bis(allenes) on application of microwave irradiation.
