Another alkaloid of A. polyneuron, polyneuridine, C21H24N2O3, differs from normacusine-B by CO2CH2. It contains a carbomethoxyl group as was shown by hydrolysis to the acid, CCCXXIV, which was... [Pg.485]

The amount available of macusine A chloride, C22H27N2O3 CP, mp 252°, [a]D —58° (in water), was initially too small for a solution of its structure by chemical means. Structural analysis by the X-ray method (80) established the constitution LIII with only the absolute configuration to be determined this is considered later in this discussion. When the structure of polyneuridine was determined (77), it was found to be the tertiary base corresponding to macusine A. [Pg.535]

This could take place as depicted in L and/or LI to generate the 248 + R ion. The former route may be more favoured in the case of polyneuridine and voachalotine than in akuammidine. [Pg.808]

The observed differences in the mass spectra of polyneuridine and akuammidine (204), which differ only in the stereochemistry at C-16,92 were later explained by a partial thermal decomposition of polyneuridine in the inlet system in which water is eliminated, (207)->[208].9° The alternative position of the CH2OH group prevents this reaction in akuammidine. [Pg.348]

An interesting example of N-oxygenated alkaloid, polyneuridine- -oxide 91, occurs in the roots of Ochrosia acuminata along with 17-hydroxy-lO-methoxy-yohimbane 92 <2004JNP1719>. [Pg.370]

At the outset we would like to emphasize the generally easy interconversion between ajmaline and sarpagine derivatives, schematically presented here for the not yet naturally found 1,2-didehydroquebrachidine (142) and polyneuridine aldehyde (143) (Scheme 9). [Pg.25]

In the original references 159 and 160 the isolated -akuammidine was erroneously identified as polyneuridine. See Jokela and Lounasmaa (239). [Pg.115]
