Gold-catalyzed oxidative cycloadditions to activate a quinoline framework
Huple, Deepak B.,Ghorpade, Satish,Liu, Rai-Shung
, p. 12965 - 12969 (2013)
Going for gold! Gold-catalyzed reactions of 3,5- and 3,6-dienynes with 8-alkylquinoline oxides results in an oxidative cycloaddition with high stereospecificity (see scheme; EWG = electron-withdrawing group); this process involves a catalytic activation o
Synthesis of substituted styrenes and 3-vinylphenols using ruthenium-catalyzed ring-closing enyne metathesis

The synthesis of substituted styrenes 3 and 3-vinylphenols 9 was achieved by ring-closing enyne metathesis (RCEM)/dehydration of 7 and RCEM/tautomerization of 8, respectively. Those methods provide selective access to unique aromatic compounds and solve the problem of regioisomer formation.
Synthetic study of the angular tetracyclic core skeleton of landmycine a via Masamune-Bergman cyclization
Yamaguchi, Sho,Tanaka, Hiroshi,Yamada, Ryo,Kawauchi, Susumu,Takahashi, Takashi
, p. 1327 - 1330 (2012/07/28)
We describe the synthesis, via Masamune-Bergman cyclization, of an angucycline derivative involving a quinone in the B ring and a nonaromatic hydroxylated C ring. The naphthoquinone was synthesized via the copper-catalyzed Ullmann reaction of the dihalo a
Palladium(0)-catalyzed alkylative cyclization of alkynals and alkynones: Remarkable trans-addition of organoboronic reagents
Tsukamoto, Hirokazu,Ueno, Tatsuhiko,Kondo, Yoshinori
, p. 1406 - 1407 (2007/10/03)
Palladium/monophosphine complexes catalyze trans-selective arylative, alkenylative, and alkylative cyclization reactions of alkynals and alkynones with organoboronic reagents. These reactions afford six-membered allylic alcohols with endo-tri- or tetrasub
