Palmatine (Scheme 1) bears the same tetracychc structure as berberine but differs in the nature of the substituents on the benzo ring being methylene dioxy for berberine and dimethoxy for palmatine. In aqueous buffer, the UV-visible spectriun of palmatine shows maxima at 232, 268, 344.5 and 420 nm. Palmatine has a weak fluorescence spectrum in the range 400-650 nm with... [Pg.174]

Friedel-Crafts acylation of benzo[6]thiophene usually gives a mixture of 2- and 3-substituted isomers, in which the 3-isomer predominates (Section 3.14.2.4). However, various electron-releasing groups elsewhere on the ring system may favor 2-acylation. Certainly 3-alkyl- or 3-methoxy-benzo[h]thiophenes are acylated exclusively in the 2-position, and 5,6-dimethoxy-, 5,6-methylenedioxy- and 6-ethoxy-benzo[f>]thiophenes are acylated predominantly in the 2-position (70AHC(11)177).

Treatment of the disulfide (90) with iodine in dioxane under various conditions gives low yields of 5,6-dimethoxy-2,3-dihydrobenzo[6]-thiophene.346 At high temperatures in ethylene glycol a mixture of this compound and the dehydrogenated product, 5,6-dim ethoxy-benzo[6]thiophene, is obtained. These observations demonstrate the importance of the double bond in the side chain of the mercapto-acrylic acids (88) in promoting their cyclization. [Pg.234]
