main side product, the HMB isomer, may be an interesting intermediate for the synthesis of calone analogues, which are important scaffolds used in fragrances. A detailed mechanisticstudy, supported by kinetics, GC-MS, and HMBC NMR characterization, is also reported. Accordingly, this paper describes a completely innovative and greener synthesis pathway to benzodioxanes.
The invention relates to a compound having the formula
where R represents hydrogen or (C1-C4) alkyl: where A represents chlorine or hydroxyl; and where B represents hydrogen, (C1-C4) alkyl, 7-coumarinyl, phosphono, phenyl, or phenyl substituted with amino, dimethylamino, hydroxyl, methoxyl, carboxyl, carboxymethyl, or 2-carboxyethenyl, which possesses depressant and/or antihypoxia activity.
本发明涉及一种化合物,其式如下
其中 R 代表氢或(C1-C4)烷基:其中 A 代表氯或羟基;以及其中 B 代表氢、(C1-C4)烷基、7-香豆素基、膦酰基、苯基或被氨基、二甲基氨基、羟基、甲氧基、羧基、羧甲基或 2-羧基乙烯基取代的苯基,该化合物具有抑制和/或抗缺氧活性。
