Formation of 3a′,8′-dimethyl-3a′,5′-dihydro-1′H,3′H-dispiro-[cyclohexane-1,3′-furo[3,4-f][2]benzofuran-5′,1″-cyclohexane]-1′,7′(4′H)-dione in the reaction of 3-acetyl-4-methyl-1-oxaspiro[4.5]dec-3-en-2-one with potassium hydroxide
摘要:
3a',8'-Dimethyl-3a',5'-dihydro-1'H,3'H-dispiro[cyclohexane-1,3'-furo[3,4-f][2]benzofuran-5',1aEuro(3)-cyclohexane]-1',7'(4'H)-dione was synthesized by reaction of 3-acetyl-4-methyl-1-oxaspiro[4.5]dec-3-en-2-one with potassium hydroxide in water.
