Rosin serves as a natural renewable resource, which is attributed to tremendous potential and advantages associated with its cheap, high output, and renewable in the development and utilization. In the perspective of rosin-based research and application of heterocyclic compounds: 2.1 The new heterocyclic compounds present, the rosin-based synthesis of heterocyclic compounds by the reaction of dehydrogenation of acid-based materials, structure, relatively undiversified; to the structure of in-depth modification of rosin, which can be synthesized type dependent that is for a variety of heterocyclic compounds. 2.2 Biotransformation of natural plant resources in combination with biological pharmacological activity of rosin-based heterocyclic compounds, such as alcohol diterpene peroxide, acid lactone compounds, synthesis of active substances with a similar structure in order to open up new medical research areas. 2.3 The areas of expansion in the synthesis of rosin-based heterocyclic compounds rely on the use of its active groups that can lead to new materials and expand its research and applications. In short, the rosin-based heterocyclic compounds have been used as an important class of potential resources for research and development, and applied to chemical, biological pesticides and medicine into the area. Therefore, rosin heterocyclic compounds have prospect of intensive research. |
