    摘要: Provided are compounds, processes and synthetic intermediates useful for the preparation of compounds of the formula I and IX wherein R1 is selected from the group consisting of hydrogen, trihalomethyl, C¿1-?C6 alkyl and substituted or unsubstituted phenyl; Y is a group of the formula wherein R?2¿ is selected from the group consisting of C¿1?-C6 alkyl, C1-C6 alkanoylamino and amino; and R?5¿ is selected from the group consisting of hydrogen, amino, halogen, hydroxyl, nitro, C¿1?-C6 alkyl, C1-C6 alkoxy, carboxy, C1-C6 trihaloalkyl, cyano, phosphonato, and hydroxyalkyl; and Z is selected from the group consisting of substituted and unsubstituted aryl. Also provided are certain N-acylated analogs of compounds of the formula I and IX, and processes for their preparation.
