Indazole 1 has previously been shown to be a potent and selective 5-HT3receptorantagonist. A novel series of potent5-HT3receptorantagonists, 1-indolinecarboxamides 2a-q and 1-indolecarboxamides 3b,i,j,k, is described. The activity of the indolines suggests that aromaticity of the 5-membered ring is not an essential requirement for potency provided that an "in plane" orientation of the carbonyl
