Abstract

This poster describes the scope and features of some new methods for the metal-free α-functionalisation of carbonyl compds. (Figure 1). A new family of reagents 1 based on an N-alkyl hydroxylamine skeleton are shown to react with both aldehydes and cyclic and acyclic ketones to generate α-functionalised products under mild conditions and in good yield. Reactions proceed in one practical step in the presence of both air and moisture, and are tolerant of a wide variety of functional groups. Addnl., in the case of non-sym. substrates the reaction proceeds with excellent regioselectivity. The reagents presented can be used to effect the first direct conversion of carbonyl compds. to α-oxy carbamates, carbonates and tosylates amongst others, and offer a valuable new technique for the synthetic chemist's toolbox.
