GC-FTR spectroscopy provides a convenient, rapid method to distinguish cis-and transit,a'disubstituted piperidines and pyrrolidines; the pyrroIicIInes usuaIIy first require N-methylation. Cis-isomers exhibit significant BobImauu bands. tram-isomers only very weak bands. The method is also applicable

## Abstract The two‐step alkylation of phenyl prop‐2‐enyl sulfone (1) with protected ω‐bromoalkanols and 1‐iodoalkanes (→3; see __Scheme 1__) followed by a Pd‐catalyzed desulfonylation with LiBH~4~ affords a 96:4 mixture of vinylbranched, protected alcohols and corresponding ethylidene‐branched iso
