##STR1## in which R.sup.1 is --COR.sup.z in which R.sup.z is RO-- or R; R.sup.g is C.sub.1-6 alkyl, C.sub.2-6 alkenyl, C.sub.2-6 alkynyl, C.sub.3-6 cycloalkyl, or a radical of the formula --W--R.sup.x in which W is a bond, C.sub.2-6 alkenediyl, or --(CH.sub.2).sub.t --, in which t is one to six; and R.sup.x is naphthyl, phenyl, or heteroaryl, and furthermore R.sup.x can be optionally substituted with one to three same or different C.sub.1-6 alkyl, C.sub.1-6 alkoxy, halogen or --CF.sub.3 groups; R.sup.2 is --OCOR, H, OH, --OR, --OSO.sub.2 R, --OCONR.sup.o R, --OCONHR, --OCOO(CH.sub.2).sub.t R, or --OCOOR; and R and R.sup.o are independently C.sub.1-6 alkyl, C.sub.2-6 alkenyl, C.sub.3-6 cycloalkyl, C.sub.2-6 alkynyl, or phenyl, optionally substituted with one to three same or different C.sub.1-6 alkyl, C.sub.1-6 alkoxy, halogen or --CF.sub.3 groups. Further provided by this invention are pharmaceutical formulations and intermediates for the the preparation of deoxy taxols of formula I. A method of treating mammalian tumors using a compound of formula I is also provided.
R.sup.1为--COR.sup.z,其中R.sup.z为RO--或R;R.sup.g为C.sub.1-6烷基,C.sub.2-6烯基,C.sub.2-6炔基,C.sub.3-6环烷基,或具有--W--R.sup.x的基团,其中W为键,C.sub.2-6烯二基,或--(CH.sub.2).sub.t--,其中t为1至6;而R.sup.x为萘基,苯基,或杂环烷基,并且进一步R.sup.x可以选择性地用一个到三个相同或不同的C.sub.1-6烷基,C.sub.1-6烷氧基,卤素或--CF.sub.3基团取代;R.sup.2为--OCOR,H,OH,--OR,--OSO.sub.2 R,--OCONR.sup.o R,--OCONHR,--OCOO(CH.sub.2).sub.t R,或--OCOOR;而R和R.sup.o独立地为C.sub.1-6烷基,C.sub.2-6烯基,C.sub.3-6环烷基,C.sub.2-6炔基,或苯基,可以选择性地用一个到三个相同或不同的C.sub.1-6烷基,C.sub.1-6烷氧基,卤素或--CF.sub.3基团取代。本发明还提供了制备式I的脱氧紫杉醇的药物配方和中间体。还提供了一种使用式I化合物治疗哺乳动物肿瘤的方法。
