Cyclizations of acyclic N-acyliminium ions, generated from the adducts of formaldehyde, n-butyl glyoxylate or methyl glyoxylate with amines containing an allyl or propargyl silane as terminator, lead to 3-ethenyl and 3-ethenylidene substituted pyrrolidines and piperidines, some of which are structurally related to proline and pipecolic acid.
