PROCEDURE

实验过程

The same reaction and isolation procedures as Synthesis Example 85 were followed except that 1.52 g of 1-cyclohexene-1,2-dicarboxylic anhydride, 1.54 g of cyclohexane-1,2-dicarboxylic anhydride, 1.12 g of citraconic anhydride, 1.66 g of norbornane-2,3-dicarboxylic anhydride, 3.71 g of 1,4,5,6,7,7-hexachloro-5-norbornene-2,3-dicarboxylic anhydride, 1.66 g of 4-methyl-4-cyclohexene-1,2-dicarboxylic anhydride or 1.78 g of 5-methyl-5-norbornene-2,3-dicarboxylic anhydride was used in lieu of 1.64 g of 5-norbornene-2,3-dicarboxylic anhydride to give the corresponding 3,4-dihydro-2H-benzopyran derivative. The results are given in Table 12. ##STR109##
