Acta Crystallographica Section E Structure Reports Online, 2013 In the title compound, C15H14O3, the dihedral angle between the benzene rings is 75.85 (7)°. In the crystal, centrosymmetrically related mol-ecules are weakly associated through pairs of inter-actions between a benzene ring and an O atom of the ester group [ring centroid⋯O = 3.952 (7) Å], and through pairs of inter-actions between the other benzene ...

The ammonolysis of esters in liquid ammonia [PDF]
, 2013 The rates of ammonolysis of alkyl benzoate and phenylacetate esters in liquid ammonia increase with the acidity of the leaving group alcohol and show relatively large Brønsted βlg values of −1.18 and −1.34, respectively, when plotted against the aqueous ...

Highly efficient synthesis of the tricyclic core of Taxol by cascade metathesis [PDF]
, 2014 An efficient enantioselective synthesis of the ABC tricyclic core of the anticancer drug Taxol is reported. The key step of this synthesis is a cascade metathesis reaction, which leads in one operation to the required tricycle if appropriate fine-tuning ...
