wherein:
L is -O-, -S-, -SO- or -SO₂-;
m and n are each independently 0 or 1;
R₁ is substituted phenyl, heterocyclyl or substitued heterocyclyl or,
when L is -O- and n is 1, R₁ is cycloheptatrienon-2-yl or,
when L is -S- and n is 1, R₁ is cyano or lower-alkoxythiocarbonyl or,
when L is -SO₂- and n is 1, R₁ is lower-alkyl or trifluoromethyl;
R₂ is hydrogen, lower-alkoxycarbonyl, phenyl or phenylthio; and
R₃ and R₄ are each hydrogen or various substituents,
and processes for preparation and pharmaceutical compositions and method of use thereof are disclosed.
