In this thesis, the author describes the total synthesis of natural product Maoecrystal V in detail. In the first part of the thesis, the author introduces the research background and reviews the research progress in total synthesis of Maoecrystal V. In the second part, the author develops a novel and concise approach for the stereo selective construction of the tetracyclic model system of Maoecrystal V. The model system is accomplished in 8 steps with 20% yield. In the third part, the author describes the first successful total synthesis of Maoecrystal V and investigates four strategies for constructing the key tetrahydrofuran oxa-bridge skeleton. The total synthesis starts from a known compound and is accomplished in 17 steps with 1.2% yield. The successful total synthesis of Maoecrystal V will contribute to the development of efficient synthetic strategies for natural products and other compounds with complex structures.

Sources show Qu Yuan (?340–278 BCE) was the first person in China to become famous for his poetry, so famous in fact that the Chinese celebrate his life with a national holiday called Poet's Day, or the Dragon Boat Festival. His work, which forms the core of the The Songs of Chu, the second oldest anthology of Chinese poetry, derives its imagery from shamanistic ritual. Its shaman hymns are among the most beautiful and mysterious liturgical works in the world. The religious milieu responsible for their imagery supplies the backdrop for his most famous work, Li sao, which translates shamanic longing for a spirit lover into the yearning for an ideal king that is central to the ancient philosophies of China. Qu Yuan was as important to the development of Chinese literature as Homer was to the development of Western literature. This translation attempts to replicate what the work might have meant to those for whom it was originally intended, rather than settle for what it was made to mean by those who inherited it. It accounts for the new view of the state of Chu that recent discoveries have inspired.
In the abandoned domain of the Mysterious Sky Continent's god race, the humans and demons continued to fight endlessly. The evil spirits had awoken unexpectedly, and the evil races from the foreign lands would descend upon the Profound Heaven Continent. Human youths occasionally obtained divine blood and became disciples of the Great Void Sect. Everything began here.
