Challenges in Structure Identification and Biogenetic Route Study in Natural Product Chemistry

摘要

The identifications and biogenetic route studies are major tasks in natural chemistry. With the developments of separation materials, and the technique of X-ray and 2D NMR, more and more novel complex compounds have been found and reported. However, a new difficulty appeared, namely, the identifications of some complex compounds, especially stereogenic centers, become a big challenge in phytochemistry when these compounds cannot form crystals, biogenetic route study for these is also a big project in this area. One example is listed below.
