Technical Notes:
1. Ligand for the enantioselective Au-catalyzed 3+3 cycloaddition reaction of 2-(1-alkynyl)-alk-2- en-1-ones with nitrones.
2.Used in enantioselective Au-catalyzed synthesis of indolyl-substituted cyclopentacfurans.
3.Used in the Au-catalyzed enantioselective synthesis of polycyclic indoline skeletons and enantiomerically enriched ß-substituted tryptamine -allenes by kinetic resolution.
