Catalytic cyclization of cis-1-ethynyl-2-vinyloxiranes was implemented with TpRuPPh 3 (CH 3 CN) 2 PF 6 catalyst (10 mol%), to give 2,6-disubstituted phenols in reasonable yields. Under similar conditions, 1,1,2,2-tetrasubstituted oxirane gave the 2,3

Catalytic cyclization of enediynes via intramolecular nucleophilic addition was achieved with TpRuPPh 3 (MeCN) 2 PF 6 and platinum dichloride, giving naphthalene-fused 2,3-dihydrofurans and -pyrroles in good yields. On the basis of experimental resul

2-Ethenyl-1-(prop-2'-yn-1'-ol)benzenes was cyclized through catalytic oxidation with PtCl(2)/CO/H(2)O and PEt(3)AuCl/H(2)O(2); the metal-naphthylidene intermediates were identified and oxygenated with water and H(2)O(2), respectively; for the efficie

PtCl2 (5 mol%) is an effective catalyst for aromatization of enediynes via a C-H bond insertion of tethered alkanes. The reaction mechanism of this cyclization is proposed to involve platinum-pi-alkyne intermediates. This cyclization works not only f
