This invention relates to novel compounds of the formula:
Y is lower alkyi; and
X and Z are independently hydrogen, halogen. lower alkyl or hydroxy, or X and Z taken together are hydroxy-imino with the proviso that when Y is methyl and Z is hydrogen. X is other than methyl or hydroxy and with the further proviso that X and Z are not both hyorogen.
本发明涉及式中的新型化合物:
Y 是低级烷基;和
X 和 Z 独立地为氢、卤素、低级烷基或羟基,或 X 和 Z 合在一起为羟基亚
氨基,但条件是当 Y 为甲基和 Z 为氢时,X 不是甲基或羟基。X不是甲基或羟基,而且X和Z不能都是次卤素。
