1-Arylnaphthalene lignan, which had been reported as a PDE4 inhibitor by Iwasaki, was disclosed as a new structural class of PDE5 inhibitors. The structural requirements for potent and specific PDE5 inhibition were revealed in a 1-arylnaphthalene lignan s

The 9-aryl-4-oxynaphthofuran-1(3H)-one system is generally synthesized in two steps from α-aryl-o-toluic acid derivatives. The method involves a tandem conjugate addition-Dieckmann type condensation between α-lithiated α-aryl-o-toluic acid derivatives and
Hydroxyacetals, phtalans, and isobenzofurans therefrom
Keay, Brian A.,Plaumann, Heinz P.,Rajapaksa, Dayananda,Rodrigo, Russell
, p. 1987 - 1995 (2007/10/02)
A general method for the generation of isobenzofuran intermediates is described.Lithiated aromatic acetals are converted to hydroxyacetals (A) which may be cyclized to isobenzofurans by mild acid treatment through the 1-hydroxyphtalans (B).The isobenzofur
Potential Isobenzofurans: their Use in the Synthesis of Naturally Occurring 1-Arylnaphthalide Lignans
Plaumann, Heinz P.,Smith, James G.,Rodrigo, Russell
, p. 354 - 355 (2007/10/02)
A three-step synthesis of seven lignans by means of a Diels-Alder reaction followed by selective borane reduction of an aromatic ester is described.
