Reaction Steps
The same reaction and isolation procedures as Synthesis Example 22 were followed except that 4.28 g of 4-benzoyloxyphenol or 3.32 g of 4-acetoxy-2-methylphenol was used in lieu of 3.04 g of trimethylhydroquinone to give the corresponding 3,4-dihydro-2H-benzopyran derivatives. The yield and FD mass spectrum of each product are given in Table 4.
