[21] Mixture of diastereomeric azides such as 3a and 3c are of high synthetic
value since they can be converted in high yield into single diastereomers
of azabicyclic compounds via a Schmidt reaction as demonstrated in our
synthesis of (–)-indolizidine 167B: A. Kapat, E. Nyfeler, G. T. Giuffredi,
P. Renaud, J. Am. Chem. Soc. 2009, 131, 17746–17747.
[22] The cis-azide 3a could be selectively prepared from the trans-alcohol 4a
via a Mitsunobu reaction with diphenylphosphoryl azide in a yield of 64%.
