New 3-O-Lauroyl-2-O-Benzyl-Glycerol Sulfonate

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.
