The process is heterogeneously catalysed using acid or basic mesoporous molecular sieves Al-SBA-15 and (Cs)Al-SBA-15. The catalytic procedure herein reported is applied to the preparation of the key intermediates for the synthesis of {3-[(2R,3R,4R,5R)-(2,3,4,5-tetrahydroxyhexane-1,6-diyl)]}di-1H-imidazole 2 with potential biomedical applications.
