In control: A new syntheticstrategy towards cyclicamines was developed and exploits a stereodefinedcyclicN,O‐acetal as the key stereocontrol and diversity‐generating element. The cyclicN,O‐acetal was prepared from the sequential asymmetric hydroamination of an alkoxyallene with the chiral ligand L*, and ring‐closing metathesis. The stereochemical integrity of the labile N,O‐acetal was conserved
