Abstract

The ruthenium tetroxide (RuO 4) oxidation of cyclic ene-carbamates resulted in the endo- cyclic carbon–carbon double bond cleavage to afford the corresponding ω-(N-formylamino) carboxylic acids in good yields. Substituted cyclic ene-carbamates derived from (3R)-3- hydroxypiperidine hydrochloride were converted into the N-Boc 4-aminobutyric acids by utilization of the RuO 4 oxidation as the key step, which were further transformed into (3R)- ...
