(S)-(+)-3-Hydroxytetrahydrofuran is an intermediate to the AIDS drugs amprenavir and fosamprenavir. Additionally, it has been an intermediate to developmental drug substances, such as chemotherapy agents.
Synthesis
(S)-(+)-3-Hydroxytetrahydrofuran was prepared from the reaction of (S)-1,2,4-butanetriol under hydrochloric acid modified montmorillonite catalyst. The steps were as follows:To the heatable reactor (with stirring device), 100g (S)-1,2,4-butanetriol, 200mL toluene, 15g hydrochloric acid modified montmorillonite catalyst prepared in were added successively. The reaction was stopped after 4 h at 110°C. After the reaction is finished, it is naturally cooled to room temperature, and the obtained material is filtered to recover the catalyst. After collecting the filtrate, the remaining solvent and by-product water in the filtrate are distilled off to obtain (S)-3-hydroxytetrahydrofuran crude product. Quantitative analysis was carried out by gas chromatography, and the yield was 96.8%. Finally, the (S)-3-hydroxytetrahydrofuran was obtained by rectification and purification.
Preperation
The preparation methods of (S)-(+)-3-Hydroxytetrahydrofuran include chiral substrate synthesis, chiral catalyst asymmetric synthesis, and enzyme-catalyzed asymmetric synthesis.
Using dimethyl L-malate as raw material, dimethyl (s)-2-tert-butyloxybutyrate was first protected by isobutene and then reduced to (s)-2-tert-butyloxybutanol with cheap NaBH4 as reductant. Finally, under the catalysis of p-toluene sulfonic acid, the product (S)-(+)-3-Hydroxytetrahydrofuran was obtained through 2-position deprotection, dehydration, and cyclization, with a yield of 65%.
