• group was confirmed by its IR spectroscopy in which the peak at 1715 cm−1 was observed. Radical azidonation of aldehyde 7 with iodine azide generated in situ by the reaction of sodium azide with ICl) at room temperature gave an acyl azide and subsequent Curtius rearrangement provided isocyanate 10 in
