Intramolecular 1,3-Dipolar Cycloaddition Strategy for Enantioselective Synthesis of FR-900482 Analogues
摘要:
[GRAPHICS]Enantioselective synthesis of FR-900482 analogues is described. The key reaction of the synthesis is intramolecular 1,3-dipolar cycloaddition of a highly functionalized nitrile oxide with complete stereo- and regioselectivities to construct the eight-membered benzazocine ring.

A metal-free electrochemical intramolecular C(sp2)–Hamination using iodine as a mediator was developed. This method enables a switchable synthesis of indoline and indole derivatives, respectively, from easily available 2-vinyl anilines.
