Publikováno v: The Journal of organic chemistry. 72(15)

On-line monitoring of Stille reactions was performed via direct infusion electrospray ionization mass spectrometry (ESI-MS) and its tandem version (ESI-MS/MS). When operated in the positive ion mode, ESI(+)-MS was able to transfer, directly from solu

The Stemona Alkaloids

Autor: Maria da Conceição F. de Oliveira, Ronaldo A. Pilli, Giovanni B. Rosso

Publisher Summary This chapter discusses the structural classification, synthesis, biological activity, and natural sources of stemona alkaloids. The Stemona alkaloids are structurally characterized by the presence of either an exposed or hidden pyrr
