Non-Existence of Multiplanar Cyclohexane Rings

摘要: THE work done by us, so far, has shown that it is possible to isolate only two forms of 4-methyl-, 3-methyl- and 2-methyleyclohexane-1-carboxy-1-acetic acids1 one form 3:3-dimethylcyclohexane-1-carboxy-1-acetic acid2. In order get more evidence on the point configuration cyclohexane ring, we have now synthesized 4:4-dimethylcyclohexane-1-carboxy-1-acetic acid 4:4-dimethylcyclohexane-1:1-diacetic from 4:4-dimethylcyclohexanone. Each them found exist in only, thus supporting uniplanar structure ring. The not yet complete, but this notice been necessary view recent publication Miller Roger Adams same subject3. full details will be published due course.
