SYNTHESIS OF 4-PHENYLCOUMARINS FROM DALBERGIA VOLUBILIS AND EXOSTEMA CARIBAEUM

Two isomeric 4-phenyl coumarins, 3',7-dihydroxy-4',5-dimethoxy-4-phenylcoumarin (seshadrin) from Dalbergia volubilis and 3',5-dihydroxy-4',7-dimethoxy-4-phenylcoumarin from Exostema caribaeum have been synthesized.However, the spectral properties of the f

An Unambiguous Synthesis of Melannein

Melannein (6-hydroxy-7-methoxy-4-(3'-hydroxy-4'-methoxyphenyl)coumarin, I) and its O,O-diethyl ether (II) have been synthesised.The steps involved in the synthesis of I and II are the respective condensation of o-methoxyhydroquinone with ethyl m-benzyloxy-p-methoxybenzoylacetate (XI) and ethyl m-ethoxy-p-methoxybenzoylacetate (III) in absolute ethyl alcohol in the presence of dry hydrogen chloride gas.The isomeric O,O-diethyl ether of melannein, viz. 6-ethoxy-7-methoxy-4(4'-ethoxy-3'-methoxyphenyl)coumarin (VI) has also been prepared by the condensation of o-methoxyhydroquinone with ethyl p-ethoxy-m-methoxybenzoylacetate (VII).The esters (III), (VII) and (XI) have been prepared by the reaction of the appropriate acetophenone derivatives with diethyl carbonate in the presence of sodium hydride.

Synthesis of (+/-)-Norruspoline

Three interesting pyrrolidine alkaloids, ruspolinone (1), norruspolinone (2) and norruspoline (7), have been isolated from Ruspolia hyperecratiformis M.R. (Acanthaceae).Norruspolinone (2) has been shown to be an early precursor in the biosynthesis of the

SYNTHESIS OF TYLOPHORINE

A biogenetic type of synthesis of tylophorine 12 (3.8percent yield, established by a radio-dilution method) was achieved by ferricyanide oxidation of 6,7-di(3-hydroxy-4-methoxyphenyl)-6,7-dehydroindolizidine 10.

Synthesis of Substituted 6,7-Diphenyl-1,2,3,5,8,8a-hexahydroindolizines

Substituted 6,7-diphenyl-1,2,3,5,8,8a-hexahydroindolizines (28a to 28e) have been synthesized by two methods.In first method, condensation of substituted 2-phenacylpyrrolidines (24b to 24d) with substituted phenylacetylchlorides (2) affords substituted 2-
