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。

donors and acceptors in organocatalytic aldol reactions. Our studies have revealed effective methodologies for accessing structurally varied and enantiomerically enriched secondary and tertiary phenylthio- and phenoxy-aldols, expanding the scope and potential synthetic utility of organocatalytic direct aldol reactions.

A series of 5,5-disubstitutedhydantoin derivatives was synthesized by alkylating 5,5-bis(mercaptomethyl)-2,4-imidazolidinedione (3) with various halomethylaromatic or halomethylheteroaromatic precursors, or by using the Buchener-Berg procedure on the required ketone. When evaluated for their ability to inhibit HIV-induced cell killing and virus production in CEM or MT-2 cells only compounds 2, 4n

Wir beschreiben eine einfache Synthese neuer Cyclohepta‐1,3‐dithiol‐6‐one 6 und 9 durch basenkatalysierte Kondensationsreaktion von 2‐Thioxo‐1,3‐dithiol‐4,5‐dicarbaldehyd 4 mit unterschiedlich substituierten Acetonderivaten.
Asymmetric Michael addition of 1,3-bis(phenylthio)propan-2-one to nitroalkenes employing Takemoto’s thiourea catalyst

AbstractAn organocatalytic direct asymmetric Michaeladdition of bis(phenylthio)propan-2-one to differently substituted aromatic nitroalkenes is described. Takemoto’s thiourea catalyst efficiently promoted this reaction under mild conditions producing the desired products in synthetically useful yields and diastereo- and enantioselectivities. A single crystallization step could further improve the
