The one genus, Alangium, of the tropics and scmilropics of the Old World, is rich in alkaloids, not all of which have had structural assignments. Considerable synonymy exists in the family. The chemistry of Alangium lamarckii has been studied in some detail and positive tests lor alkaloids were obtained from the single sample of Indian origin included in this study. [Pg.10]

Details of Kametani s synthesis66" of (i)-tubulosine and ( )-deoxytubulosine have now been published.666 An exactly analogous route has been used in the synthesis of ( )-0-methyltubulosine.66c A conventional synthesis67" of ( )-9-desmethyltubulosine (87) has revealed that it is not identical with the alkaloid, supposedly of this structure, which has been isolated from Alangium lamarckii this alkaloid, previously obtained by Popelak et al.,67b must therefore be the isomeric 10-desmethyltubulosine (88). [Pg.168]

Three new alkaloids that can be regarded as 10-aza-berberines have been isolated from Alangium lamarckii, namely alangimarine (71 R = H=CH2), alangimaridine (72), and alamarine 171 R = CH(OH)Mel. Their structures were deduced from... [Pg.112]

Deoxytubulosine has been extracted from the seeds of Alangium lamarckii.41 In connection with structure elucidation in this area, the compilations of rH n.m.r. data for geissoschizine, ajmalicine, 19-ep/-ajmalicine, tetrahydroalstonine, and rauniticine480 and of 13C n.m.r. data for diploceline19c should prove useful. The effect of stereoisomerism on the mass-spectrometric behaviour of some corynantheine and yohimbine alkaloids has also been studied.486... [Pg.185]

Alangium lamarckii is 10-desmethyltubulosine, rather than the 9-desmethyl isomer (as originally proposed), has now been confirmed by the total synthesis of ( )-10-desmethyltubulosine by a conventional sequence of reactions.61... [Pg.199]

Alangium lamarckii is a medicinal plant that accumulates tetrahydroisoquinoline monoterpene alkaloids for the production of compounds such as emetine, a constituent of ipecacuantha emetic mixture that is used to for the treatment of drug overdose. Historically, this mixture has also been used to treat amoebic dysentery by South American Indians. [Pg.194]

The structure of the monoterpenoid alkaloid alangiside (115 R = H) has been confirmed by synthesis of the O-methyl ether (115 R = Me) from secologanin and 3-hydroxy-4-methoxyphenethylamine 202 the isolation of loganic acid from the same plant (Alangium lamarckii) is consistent with biosynthetic theory.

Although known synthetically for a long time (1,14), (—)-isocephaeline (3) was not encountered in nature until quite recently. In 1980, Pakrashi s group (5) isolated this (—) base from the seeds of Alangium lamarckii Thw. and confirmed its identity with authentic isocephaeline prepared by NaBH4 reduction of psychotrine (6).

Alamarine. Pakrashi et al. (115) isolated several new types of alkaloids alamarine, alangimarine, alangimaridine, and isoalamarine from the Indian medicinal herb, Alangium lamarckii Thw. (Alangiaceae). Ninomiya et al. (73) reported the first total synthesis of alamarine (33) via the route involving enamide cyclization under both thermal and photochemical conditions. [Pg.240]
