Alcaloides de las papilionáceas. XXV. Estructura de los alcaloides adenocarpina y orensina

Chromic oxidation of orensine yields a 23 per cent C11H18N2O4, H2O and amine acid heding keto and amide groups. From this product, oxalic acid and ketodiamine (diclorhidrate, C19H18N2O, 2ClH, H2O) are obtained by acid hydrolysis. This amine acid may be obtained as well by adenocarpine oxidation. These facts and the previous one established for both alkaloids, suggest the structure of adenocarpine and orensine (racemic form) as N´-cymamoil-2’,3´-dehydro—α—β-dipiperidile.
