Issue Date: | Mar-2010 | Publisher: | Wiley-VCH | Citation: | Advanced Synthesis and Catalysis 352(4): 621-626 (2010) | Abstract: | A dual reactivity of 2-azetidinone-tethered allenols may occur by judicious choice of the electrophilic reagents, namely halogenating versus selenating reagents. Using common substrates, structurally different compounds, namely tetramic acids (from N-bromosuccinimide) or spirocyclic seleno-b-lactams (from N-phenylselenophthalimide), can be readily synthesized by these divergent protocols. | Description: | 6 páginas, 1 figura, 4 esquemas, 2 tablas.-- Comunicación en word es el articulo post-print. | Publisher version (URL): | http://dx.doi.org/10.1002/adsc.200900864 | URI: | http://hdl.handle.net/10261/29477 | DOI: | 10.1002/adsc.200900864 | ISSN: | 1615-4150 |
