| | (+/-)-MELLEIN Usage And Synthesis |
| Uses | (±)-Mellein, a marine-derived natural product, is known for its presence in Helicascus kanaloanus, exhibiting the chemical structure of 8-hydroxy-3-methyl-3,4-dihydroisochromen-1-one. | | Definition | ChEBI: Mellein is an isochromane that is 3,4-dihydroisocoumarin bearing methyl and hydroxy substituents at positions 3 and 8 respectively. It is functionally related to an isocoumarin. | | Purification Methods | Purify it by recrystallisation from H2O or aqueous EtOH. It has UV: at 247 and 314nm. [Arakawa et al. Justusmax Liebigs Ann Chem 728 152 1969, Blair & Newbold Chem Ind (London) 93 1955, J Chem Soc 2871 1955.] The methyl ether has m 66-67o and UV: 242nm ( 7,400) and 305nm ( 4,600). R(-)-Mellein has m56o(aqueous Me2CO), [] D -102.5o (c 1, CHCl3) and R(+)-mellein has m 56-57o(hexane), [] D +102o (c 1, CHCl3) or [] 25 +88o (c 1, MeOH). [Beilstein 18 III/IV 188, 18/1 V 274.] |
