Indole Prenylation in Alkaloid Synthesis
2011Important biologically active indole alkaloids are decorated with prenyl (3,3-dimethylallyl) and tert-prenyl (1,1-dimethylallyl) groups. Covering the literature until the end of 2010, this review article comprehensively summarises and discusses the currently available technologies of prenylation and tert-prenylation of indoles, which have been applied ...

The ajmaline group of indole alkaloids
2001Publisher Summary This chapter discusses an area of indole alkaloids, which has been neglected in the series for over 30 years—namely, the ajmaline group of alkaloids, where numerous advances in chemistry and biosynthesis have been made recently. The number of known ajmaline structures has grown markedly in recent years to a present count of 77. Some

Bioorganic Chemistry, 1977
Abstract Because of the nonspecific incorporation of acetate into the monoterpenoid portion of the indole alkaloids, the amino acid leucine has been investigated as an alternative precursor. Incorporations of leucine into the alkaloids vindoline and catharanthine in Vinca rosea are found to be 0.07 and 0.02%, respectively, levels comparable with ...
