Description
Technical Field
The invention belongs to the technical field of pharmaceutical chemicals, and particularly relates to a monofluoroolefin modified heteroatom cyclic lactone or lactam derivative, and a synthesis method and application thereof.
Background
Cyclolactones and lactams in heteroatoms are structural units of a variety of pharmaceutically active molecules and natural products. For example, compound I is a natural product isolated from the marine fungus Acremonium sp. AWA16-1, is cytotoxic and inhibits the growth of A549 cells (IC50 for A549 cells 27.5. mu.g/mL) (Jang, J. -H.; Kanoh, K.; Adachi, K.; Shizuri, Y.J. Nat. prod.2006,69, 1358-. The compound II has an activity of resisting rapid proliferation mycobacteria, and can inhibit the growth of Mycobacterium abscessus (Mycobacterium abscessus) (Maslivetc, V.; Turner, D.; McNairr, K.; et al, J. org. chem.2018,83, 5650-. Compound iii is an antigen-1 inhibitor associated with lymphocyte function (IC50 ═ 70nM) (watts anasin, s.; Albert, r.; ehhrhardt, c.; et al, bioorg.med. chem.2003,13, 499-. Compound IV is a key intermediate in the synthesis of 8-deoxypiperitoxin 193H, an active molecule that induces convulsions and inhibits neuromuscular activity (Zvejniece, L.; Dambrova, M.; Smits, G.Natural Product research.2021,35, 440-446.). Therefore, the development of a new method for synthesizing cyclolactone and lactam derivatives with simple and efficient heteroatom is a very important topic in the pharmaceutical and chemical fields.
Fluoroolefins are bioisosteres which are non-isomeric in amide, ester and other structural units and are difficult to hydrolyze, and are used in bioactive molecules with various pharmacological activities (anticancer, antibacterial, anti-HIV, anti-diabetic) (Taguchi, T.; Yanai, H. in Fluorine in Medicinal Chemistry and Chemical Biology; Ojima, I., Ed.; Wiley-Blackwell, Chichester, U.K., 2009; pp 257 and 290.). Thus, the introduction of fluoroolefins into heteroatoms is attractive for cyclic compound molecules in drug design. However, methods for synthesizing cyclic lactone and lactam derivatives in monofluoroolefin-modified heteroatoms have not been reported. Therefore, the development of efficient synthetic methods and strategies to construct these attractive cyclic ring molecules is currently still a challenging research topic.
