“…Chloraloses are also used as starting material for the synthesis of new compounds in carbohydrate chemistry due to potentially biological activity and stable protection in the 1,2-O-positions of theirs. Many derivatives of chloraloses have been reported such as amine [6], lactone [16], orthoesters [5,7,9], O-glycosides [7], dialdofuranose [9,17], uronic acids [17], Wittig products [18], oxime [19], spiroendoperoxide [20], thiosemicarbazone [21], and oxetane [22]. The most important ones of these derivatives, carbohydrate orthoesters, have been used very often as intermediate products in the synthesis of O-glycoside.…”
