Butanal → 3-Methyl-3,5-heptanediol

참여 물질

반응 단계

The reaction of Condition A above is repeated, except that about one mole each of butyraldehyde, isobutyraldehyde, and 2-butanone are used. The condensation and reduction proceed analogously to yield a mixture of 8-carbon-1,3-diols primarily consisting of: 2,2,4-trimethyl-1,3-pentanediol; 2-ethyl-1,3-hexanediol; 2,2-dimethyl-1,3-hexanediol; 2-ethyl-4-methyl-1,3-pentanediol; 2-ethyl-3-methyl-1,3-pentanediol; 3,5-octanediol; 2,2,3-trimethyl-1,3-pentanediol; 2-methyl-3,5-heptanediol; and 3-methyl-3,5-heptanediol, along with other minor isomers resulting from condensation on the methylene of 2-butanone instead of the methyl.
