The present invention concerns compounds of the formula: ##STR1## wherein R is a lower alkyl group, an aryl group or an alkylaryl group and X and Y are the same or different, and each is OH, NH.sub.2, or SH. The aryl group or the aryl moiety of the alkylaryl group may be unsubstituted, monosubstituted, disubstituted or trisubstituted. If substituted, each substituent may independently be an alkyl group, an alkyloxy group or a halogen. The present invention also provides methods for synthesizing the compounds described above.
本发明涉及以下结构的化合物:##STR1## 其中R是较低的烷基基团、芳基团或烷基芳基团,X和Y相同或不同,且每个都是OH、NH.sub.2或SH。芳基团或烷基芳基团的芳基或芳基基团可以是未取代的、单取代的、双取代的或三取代的。如果取代的话,每个取代基可以独立地是烷基基团、烷氧基团或卤素。本发明还提供了合成上述化合物的方法。
