A route to functionalized pyrrolizidines, indolizidines or quinolizidines is described. The reaction involves thermal cycloaddition of pyrrolidines or piperidines, possessing properly positioned aldoxime and alkene functions, and proceeds with stereospecific introduction of three stereo centers.

(R)-(2-vinylpiperid-1-yl)propanal by routine methods. Thus, by using Fukuyama’s oxime synthesis, a general method was developed for highly efficient conversion of 3-(N,N-dialkylamino)propanols into 3-(N,N-dialkylamino)propanal oximes without using the corresponding aldehydes.
