reactions starting from the chiral auxiliary p-menthane-3-carboxaldehyde. The key feature of the sequence is a highlyselective tandem Mitsunobu/3,3-sigmatropic rearrangement of hydrazoic acid that procures enantiomericallyenriched allylic azides. The sequence is either terminated by oxidative cleavage to provide amino acids or by ring-closing metathesis to provide heterocycles or carbocycles bearing nitrogen
