Strychnochrysine, a new bisindole alkaloid from <strong>the</strong> roots of <strong>Strychnos</strong> nux vomic<br />

1998<br />

Journal of Natural Products<br />

61(1): 139-141<br />

Abstract<br />

The reinvestigation of <strong>Strychnos</strong> nux-vomica resulted in <strong>the</strong> isolation of a colored monoquaternary<br />

bisindole alkaloid from <strong>the</strong> roots. The structure of this new orange substance, strychnochrysine (1),<br />

was defined by detailed spectroscopic methods.<br />

A novel route to <strong>the</strong> geissoschizine skeleton: The influence of ligands on <strong>the</strong> diast<br />

1998<br />

Tetrahedron Letters<br />

39(40): 7219-7222<br />

Abstract<br />

A concise, novel route to <strong>the</strong> geissoschizine skeleton has been developed. The key step involves a<br />

Heck cyclization reaction, which was found to lead to opposite diastereomers, (+/-)-8 or (+/-)-9,<br />

depending on <strong>the</strong> reaction conditions. (C) 1998 Elsevier Science Ltd. All rights reserved.
