6-Benzoyl-3,4-dihydro-(2H)-pyran will protect 1,2,3-triols such as glycerol as their corresponding spiro-[5-phenyl-3,6,8-trioxabicyclo[3.2.1]octane-4,2′-tetrahydropyran]s and 1,2,4-triols (less efficiently) as the corresponding trioxabicyclo[3.2.2]nonanes; the hexol mannitol is converted into the corresponding bis-protected product.
6-苯甲酰基-3,4-二氢-(2H)-吡喃能保护甘油等1,2,3-三醇,形成相应的螺环[5-苯基-3,6,8-三氧杂双环[3.2.1]辛烷-4,2'-四氢吡喃],并且(效率较低)能保护1,2,4-三醇,形成相应的三氧杂双环[3.2.2]壬烷;而六元醇甘露醇则转化为相应的双保护产物。
