実験手順
The title compound was prepared according to the procedure of Example 1 using 3-mercapto-1,2-propanediol (10.8 g, 0.1 mol), diethyl 4-oxopimelate (23 g, 0.1 mol) and boron trifluoride etherate (2.5 ml) in methylene chloride (300 ml). The crude product was chromatographed on silica gel using 40% ethyl acetate/hexane as eluent to give 14.5 g (45%) of product.
