There are provided novel 4-(2-furoyl)aminopiperidines represented by the general formula (I), their synthetic intermediates, processes for their preparation and medicaments containing them.
In the above formula, X is CH or N, and Y is a group of the following general formula (II), formula (II-a) or formula (III):
wherein a, b and c are each an integer of 0-6;
Z is CH
2
or NH; W is O or S;
T is O or N—R
15
wherein R
15
is H, a C1-C6 alkyl group, a benzyl group or a phenethyl group; and
R
1
is H, a C1-C6 alkoxycarbonyl group, a benzyloxycarbonyl group, or the like. The 4-(2-furoyl)aminopiperidine derivatives according to this invention possess opioid μ antagonistic activity and are useful for the treatment or prevention of side effects which are caused by μ receptors agonist and which are selected from constipation, nausea/emesis or itch, or for the treatment or prevention of idiopathic constipation, postoperative ileus, paralytic ileus, irritable bowel syndrome or chronic pruritus.

The invention relates to substituted N-aryl heterocycles and to the physiologically tolerated salts and physiologically functional derivatives thereof.
Compounds of the formula I
1
in which the radicals have the stated meanings, the N-oxides and the physiologically tolerated salts thereof and process for the preparation thereof are described. The compounds are suitable for example as anorectic agents.
The invention relates to a novel advantageous process for the production of compounds of the formula ##STR1## wherein n is 1, R.sub.1.sup.a is hydrogen or an amino protective group R.sub.1.sup.A, R.sub.1.sup.b is hydrogen or an acyl group Ac, or R.sub.1.sup.a and R.sub.1.sup.b together are a bivalent amino protective group, R.sub.2 is hydroxyl or a radical which, together with the carbonyl grouping --C(.dbd.O)--, forms a protected carboxyl group, and the group of the formula --N(R.sub.3.sup.a) (R.sub.3.sup.b) is a secondary or tertiary amino group, or a salt thereof with salt-forming groups. The process comprises reaction of the corresponding 3-amino compounds with borohydrides in the presence of acids.
