Compounds of the formula ##STR1## wherein R.sup.1 and R.sup.2 independently C.sub.1-17 -alkyl which is saturated or optionally interrupted by up to 8 double or triple bonds and/or optionally interrupted by an O or S atom, which is present in other than the .alpha.-position to an unsaturated C atom; or phenyl, benzyl or --C.sub.6 H.sub.4 --X--C.sub.6 H.sub.5 ring-substituted by 0 to 3 C.sub.1-6 -alkyl-(O or S).sub.1 or 0 groups, and X is oxygen, sulfur or (CH.sub.2).sub.0-3, with the proviso that when R.sup.1 is n-hexyl and R.sup.2 is undecyl or 2Z,5Z-undecadienyl, at least one of the asymmetric C-atoms present in the oxetanone ring and in the .beta.-position to the latter has the R-configuration, an enantiomer or a diastereomer thereof are described. These compounds inhibit pancreas lipase and are useful agents in the treatment of obesity, hyperlipemia, atherosclerosis and arteriosclerosis.
化合物的式子为##STR1##其中R.sup.1和R.sup.2分别独立为C.sub.1-17的饱和或不饱和烷基,其可被最多8个双键或三键所打断,或被O或S原子所打断,该原子位于不饱和C原子的α位以外; 或苯基,苄基或--C.sub.6 H.sub.4 --X--C.sub.6 H.sub.5环取代为0至3个C.sub.1-6 -烷基-(O或S).sub.1或0基团,其中X为氧、硫或(CH.sub.2).sub.0-3,但当R.sup.1为正己基且R.sup.2为十一烷基或2Z,5Z-十一二烯基时,存在于氧杂环戊酮环和在后者的β-位置上的不对称C原子中至少有一个具有R构型,其对映异构体或二对映异构体被描述。这些化合物抑制胰脂酶,是治疗肥胖症、高脂血症、动脉粥样硬化和动脉硬化的有用药物。
