Simas, Alessandro Bolis C.,Furtado, Luis F.O.,Costa, Paulo R.R.
, p. 6893 - 6895 (2007/10/03)
Novel sulphones derived from chromenes through substitution at C-4 were prepared. It has been shown that, after conjugate addition of phenyl lithium and sulphone function manipulation on the adducts, these molecules lead to isoflavan, isoflavene and isoflavanone models.
PALLADIUM CATALYSED ARYLATION OF CHROM-3-EN-4-OL ACETATES VIA THEIR TRIBUTYLTIN ENOLATES
Donnelly, Dervilla M.X.,Finet, Jean-Pierre,Stenson, Paul H.
, p. 15 - 18 (2007/10/02)
Arylation of in situ generated chrom-3-en-4-ol tributyltin enolates with aryl bromide in the presence of a catalytic amount of PdCl22 gives moderate to good yields of the corresponding isoflavanones.
Methylenation Studies of Desoxybenzoins : Characterisation of Minor Products and Debenzylation of Benzyloxyisoflavanones
Malik, M. L.,Grover, S. K.
, p. 208 - 211 (2007/10/02)
The minor products in the reaction of 2-hydroxy-4-benzyloxydesoxybenzoin and methylene iodide are found to be corresponding enol-methylene ethers and 3-iodomethyl isoflavanones as shown by spectral studies.The latter compounds also form from the correspon
