an excellent result for a Friedel–Crafts reaction with rather
complicated molecules.
The weight productivity in such processes is also an im-
portant factor and 16.9 g of 5-(4-hydroxyphenyl)hydantoin

debted to Dr. Mark A. Harmer, from DuPont Research and
development, for the generous gift of the fluorosulfonic sup-
port.
(
22.4 g of the isomers mixture) was produced per gram of
SiO2–CF2SO3Mg after three reactions (under nonoptimized
conditions). This productivity may be increased after further
recycling experiments and opens the way to possible indus-
trial applications.

In the case of zeolite catalysts, the activities and produc-
tivities are very similar to those obtained with the fluoro-
sulfonic support. Unfortunately, a significant improvement
in the para/ortho selectivity was not observed. Given its
high productivity, zeolite β-Mg was chosen as the catalyst
for the reaction between 5-bromohydantoin and the other
two aromatic molecules (entries 10–13). It can be seen that
the lower reactivities of anisole and thiophene reduce the
isolated yields to 38 and 34%, respectively. It should be
noted that these figures represent productivities of more than

diate in the synthesis of 5-arylhydantoins. The reaction with
aromatic systems is easily promoted by catalytic amounts
of both homogeneous and heterogeneous Lewis acids. The
heterogeneous catalysts not only give rise to very high pro-
ductivities, but they can also be efficiently recycled with only
a slight decrease in activity. Although the reaction with phe-
nol leads to para + ortho mixtures, other aromatics allow
the synthesis of only one isomer with total selectivity. This
method opens the way to the synthesis of enantiomerically
pure arylglycines by enzymatic kinetic resolution of the cor-
responding 5-arylhydantoins.
