The preparation of a variety of N-substituted 3-azaisotoic anhydrides 3 and 8 is described.These anhydrides reacted with thiopseudoureas to give interesting bicyclic, tricyclic, and tetracyclic heterocycles many of which are new ring systems.One such hete

ANTI-HISTAMINICS OF THE FORMULA: SPC1 wherein R1 is alkyl, alkenyl or phenalkyl, R2 and R3 are hydrogen, alkyl or alkenyl, and R is an optional substituent, are prepared by reacting a 3,4-dihydro-1,3-dioxo-1H-pyrido [2,3-d][1,3]oxazine (a 3-azaisatoic anhydride) with a S-methyl-thiopseudourea.
