Selenium dioxide oxidation reaction of (Z)-3-tributylstannyl-1-alkenyl carbamates, easily obtained from allylic carbamates precursors via Buli/TMEDA/Ti(O i Pr)4 metallation, results in formation of the corresponding 3-hydroxy-1-alkenyl carbamates in high yield. No trace of the corresponding oxo derivatives was detected. Under stoichiometric conditions, simple allyltin or (Z) or (E)-crotyltin carbamates cleanly afford the corresponding (E9-allylic alcohols whereas less stereoselective reactions are observed with more complex substrates.
