Semi-Synthesis and Total-Synthesis of Natural Product

Natural products are the components or metabolites of animals, plants, mineral substance, insects, marine organisms and microorganisms, as well as a lot of endogenous chemicals in humans and animals. The basic substances compose the natural products including proteins, peptides, amino acids, nucleic acids, enzymes, monosaccharides, oligosaccharides, polysaccharides, sugars, etc.

Benzo-oxygen Heterocyclic Natural Products

Benzo-oxygen heterocyclic natural products have abundant sources, complex structures, huge numbers and obvious biological activities in the nature, since being discovered, they have become the focus researches of organic synthesis,and have got important applications in the field of medicine, pesticide and materials.

Sesquiterpenoid natural products play an important role in pesticide insecticides, insect antifeedants and anti-hypertension. However, there are many kinds of natural antifeedant agents, including terpenes, alkaloids, and glycosides and so on. Among them, the use of alkene antifeedant is the main natural antifeedant towel. So it is important for synthesis of bicyclic sesquiterpenes.

Daphnane diterpenoids usually embrace a 5/7/6-tricyclic ring system with poly-hydroxyl groups located at C3, C4, C5, C9, C13, C14, C20 and some special ones have a characteristic orthoester motif located at C9, C13, C14. The in-vitro and in-vivo experiments of these compounds have shown that they bear a wide range of biological activities including anti-HIV, anticancer, anti-leukemic, neurotrophic, pesticidal and cytotoxic effects.

Lepadins are a growing family of cis-decahydroquinoline alkaloids. Eight lepadin alkaloids have been isolated from several marine sources including the tunicate clavelina lepadiformis and its predator the flatworm prostheceraeus vittatus (lepadins A−C). It is important for synthesis of (-)-lepadins A-C.
