ABSTRACT:
Provided are compounds, processes and synthetic intermediates useful for the preparation of compounds of the formula I and IXwherein R1is selected from the group consisting of hydrogen, trihalomethyl, C1–C6alkyl and substituted or unsubstituted phenyl; Y is a group of the formulawherein R2is selected from the group consisting of C1–C6alkyl, C1–C6alkanoylamino and amino; and R5is selected from the group consisting of hydrogen, amino, halogen, hydroxyl, nitro, C1–C6alkyl, C1–C6alkoxy, carboxy, C1–C6trihaloalkyl, 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.
