PROCEDURE

实验过程

50 mg of p-toluene sulfonic acid were added to a solution of 6.2 g of the product of Step A in 70 ml of benzene and the mixture was refluxed for 90 minutes while removing the water of reaction by passing the condensed solvent through silica gel to obtain a solution of (1R,4R,5S) 4-[dihydro-2-oxo-3-(2H)-thienyl]-6,6-dimethyl-3-oxabicyclo-(3,1,0)-hexan-2-one which was used as is for the next step.
