This invention provides compounds of Formula I having the structure: wherein: B is alkyl of 1-4 carbons or alkoxy of 1-4 carbons; R1 is aryl or Het optionally substituted with R6; R2 and R3 are each independently, alkyl of 1-4 carbons, CF3, aryl or Het substituted with R6, or R2 and R3 are combined to form a cycloalkyl or heterocyclic ring optionally substituted with alkyl, benzyl, or acyl; R4, and R5 are each independently, hydrogen, halogen, alkyl of 1-4 carbons, CO2R7, SO2NHR7, CONHR7, CN, NO2 or CF3; R6 is hydrogen, halogen, NO2, alkyl of 1-4 carbons, alkoxy of 1-4 carbons, alkylcarbonyloxy of 2-7 carbon atoms, alkylcarbonyl of 2-7 carbon atoms, CF3, or COOH; and R7 is hydrogen, alkyl of 1-4 carbons, or alkylaryl where aryl group is substituted with R6; or a pharmaceutically acceptable salt thereof, which are useful in treating metabolic disorders related to insulin resistance or hyperglycemia.
