  We have successfully developed a novel and efficient phosphine-catalyzed sequential [2+3] and [3+2] annulation reaction of gamma-substituent allenoates to construct bicyclic[3, 3, 0]octene derivatives. The protocol uses readily available gamma-substituent allenoates as the starting materials, inexpensive PBu3 as the catalyst, and the corresponding products were obtained in good to excellent yields

  (EtOH)) switched synthesis of quinolines and pyridines is illustrated from (E)-2-(1,3-diphenylallylidene)malononitriles via a Pd(II)-catalyzed photochemical process. The active catalyst [L2Pd(0)] generated serves as an exogenous photosensitizer. The process offers predominantly Z-alkenylated quinolines and pyridines in TFE and EtOH, respectively. Furthermore, large-scale synthesis and a few interesting
