yield under microwave irradiation and the obtained yield was compared with the conventional synthesis method after column purification. Different novel 3-benzoyl indolizine derivatives were synthesized by microwave irradiation. The newly synthesized compound structures were characterized by spectralanalysis such as 1H-NMR, 13C-NMR, and HRMS.

The first highly regio- and enantioselectivesynthesis of 3-allylindolizines has been developed by the sequential Rh-catalyzed asymmetric allylation and Tschitschibabin reaction. Above the 20:1 branch/linear ratio, up to a 96% yield and 99% ee could be obtained with the help of tert-butyl-substituted chiral bisoxazolinephosphine ligand.
