A convenient allylsilane-N-acyliminium route toward indolizidine and quinolizidine alkaloids
This review relates all the results that we obtained in the field of the total synthesis of indolizidine and quinolizidine alkaloids using a strategy of the addition of an allylsilane on an N-acyliminium ion. In this paper, we describe the synthesis of racemic indolizidine 167B and chiral indolizidines: (-)-indolizidines 167B, 195B, 223AB, (+)-monomorine, (-)-(3R,5S,8aS)-3-butyl-5-propylindoliz...
متن کاملIndolizidine and quinolizidine alkaloids.
This review covers the isolation, structure determination, synthesis, chemical transformations and biological activity of indolizidine and quinolizidine alkaloids from microbial, plant and animal sources. Included in the review are the hydroxylated indolizidines lentiginosine, swainsonine, castanospermine and their analogues; alkaloids from animal sources, including ants, amphibians and beetles...

متن کاملStorage of Quinolizidine Alkaloids in Epidermal Tissues
Epidermal cells of lupine leaves, petioles and stems are the main storage site for quinolizidine alkaloids with an alkaloid content of 5—6 mg/g fw (= 15 — 25 mmol/kg). Epidermal tissue also store malate and hydrogen ions and show a vacuolar pH of < 5. It is argued that the specific storage of alkaloids in the vacuoles of epidermal cells might be due to active transport via carrier proteins and ...
