Monnieria trifolia

Furoquinoline Alkaloids.—Delbine and montrifoline, the new alkaloids of Monnieria trifolia, were shown by spectroscopic studies to be 4-methoxy-furoquinolines. Delbine is a hydroxy-methoxy-dictamnine, and, as it gives kokusaginine (1 R1 = R2 = OMe, R3 = H) on reaction with diazomethane, the substituents are in positions 6 and 7 since it is not identical with helipavifoline (1 R1 = OMe, R2 = OH, R3 = H) (cf Vol. 7, p. 83), delbine apparently is 6-hydroxy-7-methoxydictamnine (14). Montrifoline was assigned structure (15) on... [Pg.86]

Bhattacharyya and Serur established the structures of delbine (54), m.p. 229-231°C, and montrifoline (56), m.p. 191-193°C, the leaf alkaloids of Monnieria trifolia direct comparison of delbine with heliparvifoline (55), m.p. 245-247°C, showed that the compounds were not identical (cf. Vol. 12, p.86). Clearly unaware of the... [Pg.109]
