(±)-Cryptone (V; R = Me) has been prepared by reduction of the enol isobutyl ether (IV; R = Me, R′ -OBui) with lithium aluminium hydride. In an analogous manner, its homologues (V; R = CH2· CH2·CH2·CHMe2 and CH 2·CH2·CH:CMe2) have been synthesised, and a preliminary account of their reaction with methylmagnesion iodide is recorded.
