Novel alcohols of the formula ##STR1## wherein R.sup.a is azido or phthalimido, R.sup.4 is alkyl, cycloalkyl, cycloalkylalkyl, aryl or aralkyl, R.sup.7 and R.sup.8 together are a trimethylene or tetramethylene group which is optionally substituted by hydroxy, alkoxycarbonylamino or acylamino or in which one --CH.sub.2 -- group is replaced by --NH--, --N(alkoxycarbonyl)-, --N(acyl)- or --S-- or which carries a fused cycloalkane, aromatic or heteroaromatic ring, and R.sup.9 is alkoxycarbonyl, monoalkylcarbamoyl, monoaralkylcarbamoyl, monoarylcarbamoyl or a group of the formula ##STR2## in which R.sup.10 and R.sup.11 each is alkyl, are described along with a process for their manufacture. These alcohols are useful as intermediates, for example in the manufacture of amino acid derivatives having antiviral activity.
化合物的式子为 ##STR1## 其中 R.sup.a 是 azido 或 phthalimido,R.sup.4 是烷基,环烷基,环烷基烷基,芳基或芳基烷基,R.sup.7 和 R.sup.8 在一起是三亚甲基或四亚甲基基团,该基团可选地被羟基,烷氧羰胺基或酰胺基取代,或其中一个 -CH.sub.2-基团被 -NH-, -N(烷氧羰基)-, -N(酰基)- 或 -S- 取代,或者带有融合的环烷基,芳香基或杂芳基环,并且 R.sup.9 是烷氧羰基,单烷基氨基甲酰基,单芳基氨基甲酰基,单芳基甲酰基或一个式子的基团 ##STR2## 其中 R.sup.10 和 R.sup.11 各自是烷基。同时还描述了制造这些化合物的过程。这些醇类化合物可用作中间体,例如在制造具有抗病毒活性的氨基酸衍生物时。
