Abstract
Levoglucosenone (1) is produced in ca. 12% yield from cellulose. The preparation is carried out under reduced pressure and in the presence of soybean oil and 2.5% phosphoric acid based on the cellulose mass. Various factors are investigated to determine the effect they have on the yield of 1 from cellulose, and the optimized procedure is given. Levoglucosenone (1) can be made on the gram scale using this process, and the vacuum distillation of the compound results in a purity of greater than 90%. This procedure is the most convenient way to make levoglucosenone on the bench top given to date.
