γ-Butyrolactone, a five-membered lactone moiety, is one of the privileged structures of diverse natural products and biologically active small molecules. Because of their broad spectrum of biological and pharmacological activities, synthetic methods for γ-butyrolactones have received significant attention from synthetic and medicinal chemists for decades. Recently, new developments and improvements in traditional methods have been reported by considering synthetic efficiency, feasibility, and green chemistry. In this review, the pharmacological activities of natural and synthetic γ-butyrolactones are described, including their structures and bioassay methods. Mainly, we summarize recent advances, occurring during the past decade, in the construction of γ-butyrolactone classified based on the bond formation in γ-butyrolactone between (i) C5-O1 bond, (ii) C4-C5 and C2-O1 bonds, (iii) C3-C4 and C2-O1 bonds, (iv) C3-C4 and C5-O1 bonds, (v) C2-C3 and C2-O1 bonds, (vi) C3-C4 bond, and (vii) C2-O1 bond. In addition, the application to the total synthesis of natural products bearing γ-butyrolactone scaffolds is described. 相似文献

Epipolythiodiketopiperazine (ETP) alkaloids are structurally characterized by the presence of diketopiperazine rings having sensitive (poly)sulfide bridges, and most of them are classified as fungal secondary metabolites. Various biological activities have been reported for members of this family, including cytotoxic, antibacterial, antimicrobial, antiviral, antitumor, antiallergic, and antimalarial activities. Notably, some of the molecules were reported to show specific inhibitory activities against certain critical enzymes. Since the supply of these compounds from natural sources is quite limited, efficient chemical syntheses of ETP alkaloids would be useful for biological studies. However, total syntheses of ETP alkaloids remain a formidable challenge in current synthetic organic chemistry because of their structural complexity. In this review article, we present an overview of synthetic approaches to the ETP alkaloids during the past 50 years, and discuss significant milestones. We also summarize the biological activities of these compounds, focusing on the molecular mechanisms. 相似文献
