YieldReaction ConditionsOperation in experiment
42% With Amberlyst 15; In N,N-dimethyl-formamide; benzene; for 48h;Reflux; General procedure: Trehalose acetals were synthesized based on a method previouslydescribed for the synthesis of 4,6,4',6'-di-O-(4-allyloxybenzylidene)-alpha,alpha-D-trehalose with some modifications[40]. The acetalization reaction was carried out using a two-neckround-bottom flask equipped with a DeaneStark trap, thermometerand reflux condenser. 30 mL of anhydrous benzene, 3.2 mL of2-, 3- or 4-allyloxybenzaldehyde and 1.13 g of Amberlyst 15 wereadded to a solution of 2.7 g (7.9 mmol) of dried trehalose in 15 mL of anhydrous DMF. The reaction was carried under reflux for 48 h.After this time, the catalyst was filtered off and benzene wasremoved under reduced pressure. A solution of the product in N,N-dimethylformamide(DMF) was treated several times with aqueous NaHCO3 and deionized water. The precipitate was washed threetimes with diethyl ether (30 mL) in order to remove x-allyloxybenzaldehyde.White powder was dried under a vacuum for 24 h.
