An effective Pd(OAc)2-PPh3 catalyzed hydroesterification of alkenylphenols with phenyl formate as CO surrogate is described. A variety of lactones are obtained in generally high yields with high regioselectivities. In one case, 76% ee is obtained with a chiral ligand.

Subject of the invention is a method for enantioselective production of an isoflavane from an isoflavone, comprising the steps: (a) selectively reducing the isoflavone, such that the 4-keto group of the isoflavone is converted to a 4-hydroxy group, and the 2,3-double bond of the isoflavone is converted to a 2,3-single bond, thereby obtaining a 4-hydroxy intermediate, and (b) reacting the 4-hydroxy intermediate with a chiral reagent, such that a chiral group is covalently attached to the C4-position of the 4-hydroxy intermediate, thereby obtaining a chiral intermediate. The invention also relates to intermediates of formulae (IV), (V), (VI) and (VII) obtainable in the inventive process.

An unprecedented catalyticasymmetric protonation of ketene dithioacetals is described. Various racemic α-aryl hydrocoumarin derivatives are transformed into enantioenriched dithioacetal-protected hydrocoumarins in the presence of a chiral Brønsted acid catalyst. A newly developed phosphoric acid, featuring the 3,5-bis(pentafluorothio)phenyl (3,5-(SF(5))(2)C(6)H(3)) substituent, is introduced. The
