日期:——
An economical, solvent-free, and metal-free method for peptidesynthesis via C–N bond cleavage using lactams has been developed. The method not only eliminates the need for condensation agents and their auxiliaries, which are essential for conventional peptidesynthesis, but also exhibits high atom economy. The reaction is versatile because it can tolerate side chains bearing a range of functional
Application of Intramolecular Enyne Metathesis to the Synthesis of Aza[4.2.1]bicyclics: Enantiospecific Total Synthesis of (+)-Anatoxin-a

A concise synthesis of the potent nAChR agonist (+)-anatoxin-a (1) has been completed in a series of only nine chemical operations and 27% overall yield from commercially available D-methyl pyroglutamate (4). The synthesis features a novel procedure for the diastereoselective preparation of cis-2,5-disubstituted pyrrolidines leading to 10, which underwent an intramolecular enyne metathesis to afford a bridged azabicyclic intermediate that was transformed into 1.
