TY - JOUR ID - 197280 AU - Dostál, Jiří - Táborská, Eva - Slavík, Jiří - Potáček, Milan - de Hoffmann, Edmond PY - 1995 TI - Structure of Chelerythrine Base JF - Journal of Natural Products VL - 58 IS - 5 SP - 723 EP - 723 PB - American Chemical Society SN - 01633864 KW - Chelerythrine Base KW - alkaloids N2 - The structure of chelerythrine free base was examined. When chelerythrine chloride [1b] was treated with aqueous K2CO3 solution, bis[6-(5,6-dihydrochelerythrinyl)] ether [3] was obtained. An excess of aqueous ammonia under the same conditions yielded bis[6-(5,6-dihydrochelerythrinyl)] amine [4]. The structures of both derivatives were determined by elemental analysis, ir, 1D and 2D nmr, eims, and cims. The formation of an unstable hydroxy adduce 2a (pseudobase) was observed in H-1-nmr experiments only. ER -
