Studies on the alkaloids of cephalotaxus: V, circular dichrosim studies on cephalotaxine alkaloids

Abstract

The CD spectra of 10 cephalotaxine alkaloids, (eg., I), were measured, and the octant rule of the aromatic chromophore in these compounds was observed An aromatic 1Lb band relates the sign and magnitude of the Cotton effect to the spatial orientation of atoms about the benzene chromophore. Thus, the Cotton effect of cephalotaxine alkaloids supports the general rule.

Key words: ALKALOID, INFRARED SPECTROPHOTOMETRY, ELEMENTAL ANALYSIS, MASS SPECTROGRAPHY, NMR SPECTROMETRY, CIRCULAR DICHROISM, SPATIAL STRUCTURE, HARRINGTONINE, CEPHALOTOXINUM
