A series of β-amino α,β-unsaturated ketones 3a-f and esters 3g-l may be conveniently prepared by dispersing ammonia (NH4OH solution), primary amines and 1,3-diketones or 1,3-keto esters on K-10 montmorillonite without solvent. This procedure was also applicable to the reactions of 3a and 3g with phenyl isocyanate and phenyl isothiocyanate which afford selectively the C-adducts 4a-d.

Reactions between 4-amino-3-penten-2-one, ethyl 3-amino-2-butenoate or 3-amino-2-butenanilide and phenyl isocyanate yield mixtures of N- and C-adducts.Quantitative data allow to check the influence of the electronwithdrawing groups in the enaminocarbonyl
