(cyclization and pinacol coupling) of the intermediate ketyl. This ring forming reaction has been applied to the construction of the fully functionalized hexahydroazepine ring of the PKC inhibitor, balanol. Initial attempts to develop an asymmetric version of this reaction indicate the use of chiral ligands based on the structure of HMPA.
