Accordingly, the present invention provides a compound of Formula I, or tautomers or isomers thereof,
1
wherein: R1 is a branched chain lower alkyl (C3 to C8), cycloalkyl (C3 to C8), alkyl-substituted alkyl (C4 to C8), bicycloalkyl, 1-adamantyl, polyhaloalkyl, trialkylsilyl, unsubstituted phenyl or substituted phenyl; R2 and R3 are independently unsubstituted or substituted aromatic rings; and R4 is hydrogen, alkyl, alkylthio, alkylthioalkyl, acyloxyalkyl, alkyl, acyl, trialkylsilyl, or cyclized together with R3 and O to form a lactone of the tautomeric form.
因此,本发明提供了一种符合式I的化合物,或其互变异构体或同分异构体,其中:R1是支链低碳链烷基(C3至C8)、环烷基(C3至C8)、烷基取代的烷基(C4至C8)、双环烷基、1-金刚烷基、多卤代烷基、三烷基硅基、未取代苯基或取代苯基;R2和R3分别是未取代或取代的芳香环;R4是氢、烷基、烷基硫、烷基硫烷基、酰氧烷基、烷基、酰基、三烷基硅基,或与R3和O一起环化形成互变异构体的内酯。
