phenoxy)-2-propanones was found to be active hypocholesterolemicagents at 10 mg/kg/day. The p-chloro- and p-methyl-substituted phenoxy compounds possess the highest activity. These compounds did not possess the estrogenic and antifertility activities of the related previously reported derivatives of the bis(beta-phenylethyl) ketone series. The 1,3-bis(p-methylphenoxy)-2-propanone (7) also lowered serum triglycerides
发现一系列的1,3-双(取代的苯氧基)-2-丙烷是有效的降胆固醇药,剂量为10 mg / kg / day。对氯-和对甲基取代的苯氧基化合物具有最高的活性。这些化合物不具有以前报道过的双(β-苯乙基)酮系列相关衍生物的雌激素和抗生育活性。1,3-双(对甲基苯氧基)-2-丙酮(7)也会降低血清甘油三酸酯和甘油,这似乎是由于血清脂肪酶水平升高和肝脂肪酶活性降低所致。肝脏减少了游离脂肪酸向复杂脂质中的掺入。胆固醇在治疗的动物中排泄更快。

A series of propanones containing combinations of aryloxy and alkoxy substituents at the 1- and 3-positions were reduced to the alcohols via asymmetric transfer hydrogenation using a tethered Ru(II)/TsDPEN catalyst. The enantioselectivities of the reductions reveal a complex pattern of electronic and steric effects which, when used in a matched combination, can lead to the formation of products of
