  Access to racemic and enantioenriched 3-methyl-4-chromanones: catalysed asymmetric protonation of corresponding enolic species as the key step

  摘要：

  Bronsted acids induced the intramolecular cyclisation of 3-aryloxypropanoic esters affording 3-methyl-4-chromanones, which have been transformed into the corresponding racemic benzyl beta-oxoesters. These latter esters, in the presence of hydrogen and catalytic amounts of both palladium and (endo, endo) aminobomeol, led to optically active chromanones with up to 75% ee through a deprotection-decarboxylation-protonation cascade reaction.

  Compounds of formula (1) wherein R' and R2 are the same or different lower alkyls, R3 is hydrogen, a lower alkyl optionally substituted with a nitrogen-containing basic group or an ion of a pharmaceutically acceptable metal, and R' is hydrogen or nitro; and the acid addition salts of said formula (1) compounds with pharmaceutically acceptable acids when R3 comprises a nitrogen-containing basic group. When R4 is nitro, R1 and/or R2 may also represent hydrogen. These compounds are useful in the treatment of hypercholesterolemia and hyperlipidemia because of their high effectiveness in reducing the level of cholesterol and lipids in the blood combined with very low general toxicities and substantially reduced hepatomegalitic effects.

  式(1)化合物 其中，R'和 R2 是相同或不同的低级烷基，R3 是氢、任选被含氮碱性基团或药学上可接受的金属离子取代的低级烷基，R'是氢或硝基；当 R3 包含含氮碱性基团时，所述式（1）化合物与药学上可接受的酸的酸加成盐。当 R4 为硝基时，R1 和/或 R2 也可以代表氢。 这些化合物可用于治疗高胆固醇血症和高血脂症，因为它们在降低血液中胆固醇和血脂水平方面效果显著，而且一般毒性极低，对肝脏的影响也大大降低。
