Novel quinazoline derivatives, comprising in the heterocyclic part of their quinazoline nucleus at least one carbonyl or thiocarbonyl group and a particularly substituted piperidinyl-alkyl side chain, said compounds being potent serotonin-antagonists.

approach that provides symmetrical, unsymmetrical, and asymmetric N-heterocyclic carbene (NHC) ligands is reported. Reaction of iodoethanol with aniline provides N-(2-iodoethyl)arylamine salts that are then converted to the corresponding iodide. Reaction with aliphatic or aromatic amines followed by triethyl orthoformate was used to provide 26 different NHC ligands.

The synthesis and characterization of new mixed-donor macrocyclicligandsincorporating nitrogen, sulfur and/or oxygen heteroatoms are described. The new 17- or 18-membered macrocyclic rings contain unsymmetrical arrangements of their heteroatoms in contrast to related, previously reported rings in which the donor sets are arranged symmetrically. The X-ray structures of the 17-membered rings incorporating
