A general and practical cross-dehydrogenative coupling protocol between readily available trisubstituted α,β-dehydro α-amino carboxylic esters and H-phosphites is described. This C(sp2)-H phosphorylation reaction proceeds with absolute Z-selectivity promoted by silver salt in a radical relay manner. The bulky tetrasubstituted β-phosphonodehydroamino acids were obtained in grams and added new modules to the toolkit for peptide modifications.

2-Phenyl-5(4H)-oxazolone (azlactone) reacts with aliphatic aldehydes upon adsorption on neutral alumina and irradiation with microwaves (2 min). The corresponding condensation products are obtained in good yields (62-78%), indicating the satisfactory res
