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。

One-pot tandem piperidinium acetate-mediated cyclocondensation of 1,3-bis-sulfonylpropan-2-ones with arylaldehydes generates tris-sulfonyl 3-arylphenols in moderate to good yields in refluxing toluene under easy-operational reaction conditions. A plausible mechanism is proposed and discussed. In the overall reaction process, water and sulfinic acid were generated as the byproducts. Various ammonium
Access to 2‐Sulfonyl‐4‐arylphenols and 2,6‐Bis‐sulfonyl 5‐Aryl‐4‐arylidene‐2‐cyclohexenones via Metal Triflates‐Catalyzed Domino Cyclocondensation of 1,3‐Bis‐sulfonylacetones and 3‐Arylacroleins

Herein, metal triflates–catalyzed one-pot domino cyclocondensation of 1,3-bis-sulfonylacetones and 3-arylacroleins via (3+3) or (3+2+1) annulation has been proposed to construct diversified 2-sulfonyl-4-arylphenols and 2,6-bis-sulfonyl 5-aryl-4-arylidene-2-cyclohexenones. In this effective reaction, C−C and C=C bonds are formed via a cascade process and 3-arylacrolein acts as a C3 and C1 synthon during
