Abstract
One-pot reactions reduce reagent amounts and circumvent process treatments, such as work-up and purifications in multi-step reactions. In this study, we achieved the formal total synthesis of riccardin C through a one-pot reaction by simultaneously linking four units through two Sonogashira coupling reactions and one Suzuki coupling reaction, followed by reduction and deprotection. Thus, this one-pot method comprised five steps and did not require the purification of intermediate reaction mixtures, which saves resources, such as reagents and solvents, and expedites the work process.

Abstract
The Marchantiophyta (liverworts) are rich sources of phenolic substances, especially cyclic and acyclic bis-bibenzyls, which are rare natural products in the plant kingdom, together with bibenzyls and characteristic terpenoids. At present, more than 125 bis-bibenzyls have been found in liverworts. They are biosynthesized from the dimerization of lunularic acid via dihydrocoumaric acid and prelunularin. The structurally unusual cyclic and acyclic bis-bibenzyls show various biological activities such as antimicrobial, antifungal, cytotoxic, muscle relaxation, antioxidant, tubulin polymerization inhibitory, and antitrypanosomal activities, among others. The present review article deals with the distribution and structure of bis-bibenzyls, bibenzyls, and several characteristic ent-sesqui- and diterpenoids in liverworts. Furthermore, the biosynthesis and total syntheses and biological activities of bis-bibenzyls are also surveyed.

Abstract
![]()
Thiocyanates, versatile
building blocks in organic synthesis, are
shown to be easily accessible via an interrupted Pummerer reaction
of sulfoxides. This facile dealkylative functionalization proceeds
under mild conditions through electrophilic activation of the sulfoxide
partner. The resulting thiocyanate itself can serve as a handle for
diversification in a straightforward one-pot procedure.

Abstract
We previously showed that a naturally occurring macrocyclic bis(bibenzyl) derivative, riccardin C (RC), exhibits antibacterial activity towards methicillin-resistant Staphylococcus aureus (MRSA), with a potency comparable to that of the clinically used drug vancomycin. Here, we synthesized a series of RC derivatives to explore the structure-activity relationships (SAR). The SAR results clearly indicated that the number and positions of the phenolic hydroxyl groups are primary determinants of the anti-MRSA activity. Pharmacological characterization of the macrocyclic bis(bibenzyl) derivatives, together with fragment compounds and their dimers, indicated that the macrocycles and the fragment compounds elicit anti-MRSA activity with different mechanism(s) of action. The macrocyclic bis(bibenzyl)s are bactericidal, while the fragment compounds are bacteriostatic, showing only weak bactericidal activity. Treatment with a macrocyclic bis(bibenzyl) derivative significantly changed the intracellular Na+ and K+ concentrations of Staphylococcus aureus, and transmission electron microscopy revealed that treated cells developed intracellular lamellar mesosomal-like structures. These results indicated that the macrocyclic compound directly damages the gram-positive bacterial membrane, resulting in increased permeability.

Abstract
Little attention has been paid to the bryophytes for use in the human diet in spite of the presence of 23,000 species in the world. Some liverworts produce lipophilic terpenoids and phenolic bis-bibenzyls, possessing antimicrobial, antifungal, antiviral, cytotoxic, anti-oxidant, muscle relaxing, and antiobesity activities. In this review, the isolation, structures elucidation, bio- and total syntheses of bis-bibenzyls from several liverworts are discussed.

Abstract
We synthesized three geometrical isomers of a macrocyclic bis(bibenzyl) based on isoplagiochin, a natural product isolated from bryophytes, and evaluated their antibacterial activity towards methicillin-resistant Staphylococcus aureus (anti-MRSA activity). The isomer containing a 1,4-linked ring (5) showed only weak activity, whereas the isomers containing a 1,3-linked (6) or 1,2-linked (7) C ring showed potent anti-MRSA activity. Molecular dynamics calculations indicated that these differences are probably due to differences in the conformational flexibility of the macrocyclic ring; the active compounds 6 and 7 were more rigid than 5. In order to understand the action mechanism of anti-MRSA activity, we investigated the cellular flux of a fluorescent DNA-binder, ethidium bromide (EtBr), in the presence and absence of these macrocycles. The active compound 6 increased the levels of EtBr inflow and outflow in S. aureus cells, as did our potent anti-MRSA riccardin derivative (4), indicating that these compounds increased the permeability of the cytoplasmic membrane. Inactive 5 had no effect on EtBr inflow or outflow. Furthermore, compound 6 abrogated the normal intracellular concentration gradients of Na(+) and K(+) in S. aureus cells, increasing the intracellular Na(+) concentration and decreasing the K(+) concentration, while 5 had no such effect. These results indicate that anti-MRSA-active macrocyclic bis(bibenzyl) derivatives directly damage the gram-positive bacterial membrane, resulting in increased permeability.
