Abstract

-Two new indole alkaloids, subincanadine G (1) and pausperadine A (2), were isolated from the barks of Aspidosperma subincanum Mart and Geissospermum vellosii Allemão, respectively. Subincanadine G (1) has 1-azoniatricyclo[4.3.3.01,5]undecane moiety, while pausperadine A (2) contains an N-oxide moiety. The gross structures and relative stereochemistry of 1 and 2 were elucidated by spectroscopic data. © 2005 The Japan Institute of Heterocyclic Chemistry.
