Abstract Earlier we noted that the hydroboration of the trimethylsilyl enol ether of an acyclic ketone results in an elimination of a trimethylsiloxyborane moiety with the subsequent formation of an olefin. 1, 2 The olefin formed then undergoes hydroboration giving a monoalcohol upon oxidation.(eq 1) We wish to report here on the utility of this sequence, illustrated in eq 1, in the reductive 1, 2 transposition of acyclic ketones. 3
