1H-Indole, 2-propyl- → 3,5-bis(1-n-propyl-2-methyl-3-indolyl)-5-(1-ethyl-2-methyl-3-indolyl)-2(5H)-furanone

Participants

Reaction Steps

Following a procedure similar to that described above in part B of this example by using 2,4-bis(6-chloro-2-phenyl-3-indolyl)-4-oxobutanoic acid instead of 2,4-bis(1-n-propyl-2-methyl-3-indolyl)-4-oxobutanoic acid, and 2-propylindole is substituted for 1-ethyl-2-methylindole, there is obtained 3,5-bis-(6-chloro-2-phenyl-3-indolyl)-5-(2-propyl-3-indolyl-2(5H)-furanone (Formula III: R=R2 =Y1 =H; R1 =C6H5 ; R3 =CH3CH2CH2 ; Y=6-Cl).
