A simple, efficient, and facile synthetic route for the preparation of indole-2-carboxylicesters was described. The cascade reactions of 2-bromobenzaldehyde and glycine ester hydrochloride were promoted by Cu2O and a base to provide the corresponding products in good yields. Commercially available, inexpensive substrates and reagents were employed under mild reaction conditions in this one-pot operation

The present invention relates to cholecystokinin (CCK)-agonist substituted thiazoles of formula:
in which R1 is a substituted phenyl group, R2 is a group chosen from CH2—R7, (CH2)2—R7, S—CH2—R7, CH2—S—R7 and (C5-C8)alkyl with R7 being a (C5-C7)cycloalkyl group, and R3 is a group
with R8 being a group (CH2)nR15 or
and R15 being COOH or COO(C1-C4)alkyl. The invention also relates to a process for the preparation of the pharmaceutical compositions containing them and to their uses for the preparation of medicines.

Novel piperazin-2-one containing compounds of general formulae (I) or (II), including their pharmaceutically acceptable isomers, salts, hydrates, solvates and prodrug derivative having activity against mammalian factor Xa are described. Compositions containing such compounds are also described. The compounds and the compositions are useful in vitro or in vivo for preventing or treating conditions in mammals characterized by undesired thrombosis.
