| Título: | Microwave-promoted synthesis of bicyclic azocine-β-lactams from Bis(allenes) |
Autor: | Alcaide, Benito CSIC ORCID; Almendros, Pedro CSIC ORCID ; Aragoncillo, Cristina CSIC ORCID; Fernández, Israel; Gómez-Campillos, Gonzalo | Fecha de publicación: | 2014 | Editor: | American Chemical Society | Citación: | Journal of Organic Chemistry 79: 7075- 7083 (2014) | Resumen: | 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. This selective carbocyclization reaction has been studied experimentally, and additionally, its mechanism has been investigated by a DFT study. | URI: | http://hdl.handle.net/10261/102042 | DOI: | 10.1021/jo501231q | Identificadores: | doi: 10.1021/jo501231q issn: 0022-3263 e-issn: 1520-6904 |
