The present invention provides stereoselective processes for the preparation of compounds of formula (I)
wherein
P is phenyl, naphthyl, a 6-membered heteroaryl group containing one or two nitrogen atoms as ring members, or a 10-membered bicyclic heteroaryl group containing one or two nitrogen atoms as ring members, and wherein the phenyl, naphthyl and heteroaryl groups are optionally substituted;
R
1
is chlorodifluoromethyl or trifluoromethyl;
R
2
is optionally substituted aryl or optionally substituted heteroaryl;
n is 0 or 1;
including the process comprising
(a-i) reacting a compound of formula II
wherein P, R
1
and R
2
are as defined for the compound of formula I;
with nitromethane in the presence a chiral catalyst to give a compound of formula III
wherein P, R
1
and R
2
are as defined for the compound of formula I; and
(a-ii) reductively cyclising the compound of formula III to give the compound of formula I.
The invention also provides intermediates useful for processes for the synthesis of compounds of formula (I).
