Acta Crystallographica Section E Structure Reports Online, 2008 The structure of the title compound (4BPBA), C(13)H(9)BrO(2), is similar to that of phenyl benzoate (PBA), 4-methyl-phenyl benzoate (4MePBA) and 4-methoxy-phenyl benzoate, with somewhat different bond parameters. The dihedral angle between the phenyl and benzoyl rings in 4BPBA is 58.43 (17)°, compared with values of 55.7° in PBA and 60.17 (7)° in 4MPBA.

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 ...
