R. Breslow et al., GEOMETRICALLY DIRECTED SELECTIVE STEROID HYDROXYLATION WITH HIGH TURNOVER BY A FLUORINATED ARTIFICIAL CYTOCHROME-P-450, Tetrahedron letters, 39(19), 1998, pp. 2887-2890
A metalloporphyrin has been synthesized carrying a beta-cyclodextrin g
roup on tetrafluorophenyl rings at the four meso positions of the porp
hyrin. It performs the selective hydroxylation of an androstanediol de
rivative with complete positional selectivity and 187 turnovers. (C) 1
