The hydroxy groups of D-mannitol were protected by the formation of acetals and benzylethers and then 2-O-benzyl-D-glyceraldehyde dimethylacetal was prepared after the deprotection and oxygenolysis of the protected D-mannitol. In the presence of DCC and DMAP, the lauroyl group was introduced at the primary hydroxyl group of the dimethylacetal and 3-O-lauroyl-2-O-benzyl-glycerol was obtained after the deprotection of the dimethylacetal with FeCl3·6H2O and then reduction with NaBH4. A series of new 3-O-lauroyl-2-O-benzyl-glycerol sulfonates was synthesised by the coupling of different sulfonyl groups with the 3-O-lauroyl-2-O-benzyl- glycerol. The bioactivities of the title compounds were tested and some compounds exhibited fungicidal activity against the tested fungi.
D-mannitol 的羟基通过形成乙缩醛和苄基醚而得到保护,然后在对受保护的 D-mannitol 进行脱保护和氧解后制备出 2-O-苄基-D-甘油醛二甲基缩醛。在 DCC 和 DMAP 的存在下,在二甲基缩醛的伯羟基上引入月桂酰基,然后用 FeCl3-6H2O 对二甲基缩醛进行脱保护,再用 NaBH4 还原,就得到了 3-O-月桂酰基-2-O-苄基甘油。通过不同磺酰基与 3-O-lauroyl-2-O-benzyl- glycerol 的偶联,合成了一系列新的 3-O-lauroyl-2-O-benzyl- 甘油磺酸盐。对标题化合物的生物活性进行了测试,其中一些化合物对测试的真菌具有杀菌活性。
