实验过程

To a solution of (2S,3R)-3-(n-butyl)-2-hydroxysuccinic acid B-4 (300 mg, 1.58 mmol) in 2,2-dimethoxypropane (10 mL) is added p-TSA (20 mg) and the reaction is stirred at rt for 16 hours. The solution is diluted with DCM and washed with brine, dried (Na2SO4) and then purified by silica gel chromatography to afford 1.2 mmol 2-(2,2-dimethyl-4-oxo-1,3-dioxolan-5-yl)hexanoic acid B-5.
