3-Chloropropenyl alkyl ketones or 2-methoxy-3-chloropropyl alkyl ketones in reaction with ethylenediamine furnish previously unknown 2-alkyl-1-(2-aminoethyl) pyrroles. Their reaction with 2,2'-dichlorodiethyl ether gave rise to 2-alkyl-1-(2-morpholinoethyl)pyrroles, and with anhydrides of dicarboxylic acids the corresponding amidoacids and imides of dicarboxylic acids were obtained.

yields with excellent chemoselectivities via a Pictet-Spenglerreaction under mild and operationally simple conditions. The synthetic utility of this protocol was further extended by the facile preparation of indole-fused CF3-1,4-diazocane and enantioenriched CF3-piperazines via a vinylogous Pictet-Spenglerreaction and an asymmetricPictet-Spenglerreaction, respectively.
