Reaktionsschritte

1-Octanoyl-rac-glycerol (10.00 g, 45.81 mmol) and DMAP were placed in a flame-dried round bottom flask, followed by triethylamine (13.0 ml, 93.27 mmol) and CH2Cl2 (200 ml). When the solid dissolved, trityl chloride (14.07 g, 50.47 mmol) was added and the mixture was stirred at room temperature for two days. The mixture was poured into ice water and the two phases were separated. The organic layer was washed three times with 1 N HCL and twice with water, dried over MgSO4, and evaporated. The product was purified by chromatography in two batches, (150 g silica gel each with hexanes:ethyl acetate (8:1) solvent) to yield compound 43, 1-octanoyl-3-O-trityl-rac-glycerol (9.96 g, 47% yield).
