실험 절차
By following the procedure of part A and substituting methyl (E) 6(4-t-butyldimethylsilyloxy-1,3-dihydro-6-methoxy-7-methyl-3-oxoisobenzofuran-5-yl)-4-methyl-4-hexenoate with (E) 6-(1,3-dihydro-6-methoxy-4-methoxyethoxymethoxy-7-methyl-3-oxoisobenzofuran-5-yl)-4-methyl-4-hexenoic acid, there was obtained 2-(1,3-dihydro-6-methoxy-4-methoxyethoxymethoxy-7-methyl-3-oxoisobenzofuran-5-yl)-acetaldehyde, m.p. 61°-63° C. (hexane-ethyl acetate).
