A series of phenylbutene and butanol derivatives (6a-j, 12, 13, 15, 17, 24b,c, 26, 27a,b) were prepared from the readily available resorcinol derivatives 2a-f and 7-hydroxy-chroman (18). The products were tested for inhibitory activity on the LPS-induced

, p. 3958 - 3973 (2007/10/02)
The scope and limitations of alkenyl dienone cyclizations for the formation of fused cyclooctane or cyclohexane systems are described.
REGIOSPECIFIC ALKENYLATION OF PHENOLS BY ISOPRENE PROMOTED BY Pt(II) AND Pd(II) COMPLEXES
Felice, Vincenzo De,Renzi, Augusto De,Funicello, Maria,Panunzi, Achille,Saporito, Antonio
, p. 13 - 16 (2007/10/02)
Catalytic alkenylation of phenols with isoprene is promoted by Pd(II) or Pt(II) complexes.Ortho-isopentenylphenols are obtained together with the corresponding 2,2-dimethylchromans.The catalytic activity of the two d8 ions is compared.A possible mechanism is discussed.
REGIOSPECIFIC ALKENYLATION OF PHENOLS BY 1,1-DIMETHYLALLENE PROMOTED BY PLATINUM CATALYSTS
Renzi, Augusto De,Panunzi, Achille,Saporito, Antonio,Vitagliano, Aldo
, p. 993 - 996 (2007/10/02)
1,1-Dimethylallene reacts with phenolic substrates in the presence of catalytic amounts of platinum(II) complexes.A regiospecific C-alkenylation takes place, affording o-isopentenylphenols and 2,2-dimethylchromans.Possible reaction mechanisms are also discussed.
