A series of 1,3-bis(substituted phenoxy)-2-propanones, long-chain ketones, and relatedderivatives has been synthesized, and it has been found that certain analogues produce significant lowering of serum cholesterol levels in Sprague-Dawley rats. These compounds possess no estrogenic properties and are nontoxic at 10 mg/kg/day. Physical studies on these compounds include an attempt to correlate hypocholesteremic
已经合成了一系列的1,3-双(取代的苯氧基)-2-丙烷,长链酮和相关的衍生物,并且已经发现某些类似物在Sprague-Dawley大鼠中产生血清胆固醇水平的显着降低。这些化合物不具有雌激素特性,在10 mg / kg / day时无毒。对这些化合物的物理研究包括尝试将降胆固醇活性与化合物的亲脂性,电子和空间位阻联系起来。测量某些衍生物的1-辛醇-H2O分配系数,并计算取代基的pi常数。芳香族取代基的哈米特σ常数从文献中获得。

pterocarpenes and coumestans is described. BCl3-mediated dehydrative cyclization of 1,3-diaryloxyacetones under mild conditions permitted regioselective ring closure to afford 3-((2-iodoaryloxy)methyl)benzofurans which were converted to the corresponding pterocarpenes by Pd-catalyzed intramoleculardirectarylation. The subsequent benzylic oxidation led to coumestans. This sequence was applied to the formal
