13. Preliminary studies using the ketal-protected amino ketone iii lacking the o-hydroxybenzyl substitution at nitrogen indicated that deprotection followed by exposure to reductive amination conditions did not result in cyclization to the expected azabicyclo skeleton iv, but instead gave a complex mixture
