Several methods', including one recently reported3 by us, are available for the synthesis of ketimines. However, 4 we are not aware of any general route to a-diketimines . We now report
A specific strategy is described for the synthesis of stable demonstrated: (i) the low reactivity of PEO derivatives, and (ii) the necessity of a stabiliser arm between the cyclam and polyethylene oxide tagged tetraazamacrocycles (PEOcyclam) in five steps (overall yields for 12 and 13 48% and the PE
