A large variety of target compounds is prepared under mild conditions using a four-component Biginelli-type reaction. The method is general for aromatic and heteroaromatic aldehydes, including bisaldehydes, but is not applicable to aliphatic substrates. For the formation of (VII), the conditions have to be changed. -(HULME*, R.; ZAMORA, O. D. P.; MOTA, E. J.; PASTEN, M.
