Furans are versatile synthons in organic chemistry. Described is a general method for transforming furans into alkynes by dual C−C double‐bond cleavage. The reaction is proposed to proceed by sequential [4+2] cycloaddition between furan and singlet oxygen and a formal retro‐(3+2) fragmentation of the endoperoxide intermediate. A wide array of furans, including those derived from sapogenins, are amenable...
Dengue virus nonstructural protein 4B (NS4B) is a membrane protein consisting of 248 residues with a crucial role in virus replication and interference with the host innate immunity. The dengue virus serotype 3 NS4B was reconstituted into lyso‐myristoyl phosphatidylglycerol (LMPG) micelles. Backbone resonance assignment of NS4B was obtained using conventional solution NMR experiments. Further studies...
