PMID: 27062363
Photoinduced intramolecular direct arylation allows structurally unique compounds containing phenanthro[9',10':4,5]imidazo[1,2-f]phenanthridine and imidazo[1,2-f]phenanthridine skeletons, which mediate excited-state intramolecular proton transfer (ESIPT), to be efficiently synthesized. The developed polycyclic aromatics demonstrate that...

Carbanions of aryl 3-chloropropylsulfoxides react with nonenolizable aldehydes to give 2,3-disubstituted tetrahydrofurans. Deprotonation of the sulfoxides carried out in the presence of aldehydes results in the addition of the carbanions...

PMID: 18770510
Three naphthalene-based analogues (4 a-c) of the Hoveyda-Grubbs metathesis catalyst exhibited immense differences in reactivity. Systematic structural and spectroscopic studies revealed that the ruthenafurane ring present in all 2-isopropoxyarylidene chelates...
