[reaction: see text]An efficient formal synthesis of the potent protein kinase C inhibitor (-)-balanol that relies on a modified asymmetric aminohydroxylation of the alpha,beta-unsaturated aryl ester (1) is reported. The aryl ester functionality and the dihydroquinyl alkaloid ligand system (DHQ)2-AQN are used to control the regio- and enantioselectivity of the process.

A stereodivergent route to four stereoisomeric azepane derivativesrelated to the important protein kinase inhibitor balanol is developed which utilises (−)- or (+)-serine as starting material, and a ring-closing metathesis as the key ring forming step.
