The present invention relates to a 5-tert-butyloxycarbonyl-2-oxa-5-azabicyclo[2.2.1]heptane-1-carboxylic acid synthesis method. In the prior art, the suitable industrial synthesis method does not exist. A purpose of the present invention is mainly to solve the technical problem in the prior art. The synthesis method comprises six steps, and specifically comprises that a compound 1 and Boc anhydride react under an alkaline condition to obtain a compound 2, the compound 2 is oxidized into a compound 3 by using a 2,2,6,6-tetramethyl piperidine oxide, the compound 3 reacts with a Grignard reagent to obtain a compound 4, the carboxylic acid 4 is reduced with lithium aluminum hydride to obtain a compound 5, the compound 5 reacts with n-butyl lithium and p-tosyl chloride in two stages to obtain a compound 6, and the compound 6 is oxidized with sodium periodate to obtain a final compound 7. The reaction formula is defined in the specification.
