A catalyst-free one-pot construction of skeletons of 5-methoxyseselin and alloxanthoxyletin in water

In refluxing water and without an additional catalyst, electron-rich phenols could react with alkynoic acids or alkynoates to provide coumarin structures. The skeletons of two natural pyranocoumarins, 5-methoxyseselin and alloxanthoxyletin, could be constructed (total yield up to 76%) in an aqueous multicomponent reaction in which isoprenyl acetate, propiolic acid, and phloroglucinol were simply mixed and refluxed in water.

Natural Product Chemistry. Part 121. Synthesis of Dicoumarinyl Ethers with the Structures Proposed for Fatagarine and Oreojasmine

Synthesis of the 7,8'-dicoumarinyl ethers: 7-methoxy-7',8-oxydicoumarin and 6,7-dimethoxy-7',8-oxydicoumarin, established that the structures of fatagarine and oreojasmine for which these two structures have been proposed, have to be revised.Synthesis of 7-methoxy-5,7'-oxydicoumarin and 8-methoxy-7,7'-oxydicoumarin exclude the possibility of these dicoumarinyl ether structures for fatagarine. - Keywords: Dicoumarinyl ethers; 6,7-Dimethoxy-7',8-oxydicoumarin; Fatagarine; 7-Methoxy-5,7'-oxydicoumarin; 8-Methoxy-7,7'-oxydicoumarin; 7-Methoxy-7',8-oxydicoumarin; Oreojasmine; Ruta oreojasme
