| titleOfInvention | 3-Methyl-2-Methyl:butenyl-furan prepn. |
| abstract | Prepn. of 3-methyl-2- 3-methylbut-2-ene-1-yl -furan (I) is new. In a first stage, 2 methylprop-2-enyl chloride is added to 3-methylpent-1-ene-4-yne-3-ol or to 3-methyl-pent-2-ene-4-yne-1-ol to give 3, 7-dimethylocta-1,7-diene -4-yne-3-ol or 3,7-dimethylocta-2,7-diene-4-yne-1-ol respectively. The resulting carbinol cpds. are then treated with a cyclisation agent to give 3-methyl-2- 3-methyl-but-3-ene-1-yl -furan. The terminal double bond of this cpd. is then isomerised by thermal treatment in the presence of Pd-on-C to give (I)The process can be used on an industrial scale and uses relatively cheap and easily-obtainable starting materials compared with previous processes. |
