Criteria for the elucidation of the pseudopericyclic character of the cyclization of (Z)-1,2,4,6-heptatetraene and its heterosubstituted analogues: magnetic properties and natural bond orbital analysis.
Rodríguez-Otero J, Cabaleiro-Lago EM. Rodríguez-Otero J, et al. Chemistry. 2003 Apr 14;9(8):1837-43. doi: 10.1002/chem.200390211. Chemistry. 2003. PMID: 12698442
The electrocyclization of heterosubstituted derivatives of (Z)-1,2,4,6-heptatetraene, (2Z)-2,4,5-hexatrien-1-imine and (2Z)-2,4,5-hexatrienal exhibit some features which suggest a pseudopericyclic mechanism. In order to examine this, a comprehensive st …
