Boron trifluoride complex of magnesium dihomoallylcuprate, (CH2=CHCH2CH2)2CuMgBr.BF3, reacted wlth aldimines containing α-hydrogen to afford the corresponding addltion products in good yields. The addition products were converted to pyrrolidine derivatives by treatment with phenylselenenyl chloride in the presence of trifluoroacetic acid and silica gel.
