afforded the corresponding azido-alcohols 11 and 12, isolated as single stereoisomers in excellent yield (95–98%). No other isomer of 11 or 12 was detected by NMR analysis, indicating that the ring-openingreaction is highly regioselective and results in the anti addition of the azido group on the opposite
