| titleOfInvention | Synthesis of 8-membered carbocyclic compound having diexomethylene groups |
| abstract | The present invention relates to a synthesis of an 8-membered carbocyclic compound having diexomethylene groups, more particularly to a synthesis of an 8-membered carbocyclic compound having diexomethylene groups, a novel compound having the structure represented by the following Chemical Formula 1, from trimethylsilanylmethyl-allenol derivative by the intramolecular Prins cyclization using Lewis acid. The 8-membered carbocyclic compound is a useful intermediate for synthesis of other multicarbocyclic compounds. n n n In Chemical Formula 1, R 1 is a phenyl group, and R 2 and R 3 is a hydrogen atom, or R 1 , R 2 and R 3 may be connected with neighboring substituents to form a 5 to 10-membered aliphatic or aromatic ring. |
