The nucleophilic ring-opening of tosylaziridines with chiral aza-enolates is reported. The SAMP-/ RAMP-hydrazones 1a−h derived from aldehydes or ketones were reacted with tosylaziridine 2a to give the β-aminoethylated hydrazones 3a−h with good d

The asymmetric synthesis of g-amino nitriles 4a-c and g- amino ketones 5d-f is described. Key step of the procedure is the diastereoselective b-aminoethylation of metalated SAMP-/RAMP- hydrazones 1a-f with tosylaziridine 2. Cleavage of the chiral aux

[structure: see text] The unusual [5.3.2]-bicyclic structure of the insecticidal Amaryllidaceae alkaloids cripowellin A (1) and B (2) has been synthesized for the first time via a sequence of Sharpless dihydroxylation, ring-closing metathesis, and in
