—— | 2,4-Dimethoxy-6-(2-propyl-[1,3]dioxolan-2-ylmethyl)-benzoic acid ethyl ester | 193617-48-0 | C18H26O6 | 338.401 |
The unambiguous total synthesis of the lichen depsides 2-O-methylglomelliferic acid (39), 4-O- methylhyperolivetoric acid (40), hyperconfluentic acid (41), microphyllinic acid (42), arthoniaic acid (43), 2′-O-methylmicrophyllinic acid (44), 2′-O-methylhyperphyllinic acid B (45), 4-O-methylsuperolivetoric acid (46), 2′-O-methylhyperphyllinic acid A (47), 2′-O-methylnorsuperphyllinic acid (48) and 4-O- methyloxocryptochlorophaeic acid (49) has been achieved by the condensation of an appropriately substituted orsellinic acid and protected phenol in the key step, followed by deprotection.
