As an excellent functional system, brains are capable of computation and communication through efficient performance with low cost.However, how the cost-efficiency trade-off is achieved is not fully u
Enantioselective protonation is one of the most straightforward, yet challenging approaches for constructing tertiary stereogenic carbon centers, particularly α-chiral carbonyl compounds.[1] In this r
During the past several years, Pd-catalyzed ligand-directed sp2 C-H functionalization has advanced rapidly.The groups of Sanford and Ritter have reported on the Pd-catalyzed oxygenation of organic sub
The Diels-Alder reaction, [4+2] cycloadditions between electronically matched dienes and dienophiles, is one of synthetic organic chemists text-book reactions.[1] Though Brφnsted acids or Lewis acids
Development of novel macrocyclic hosts with the capability of binding selected substrates in specific complexation modes is always a very important and attractive topic in host-guest chemistry.Recentl
Fluorescent dyes have attracted a considerable amount of interests due to their nondestructive nature,rapid response times and a wide range of potential applications as fluorescent probe, biological s
Pentiptycene[1,2] has the unique H-shaped structure, which is inherently different from the Y-shaped scaffold of triptycene.Thus, pentiptycene derivatives can be used as a new class of useful building
