| titleOfInvention | Production method of? -toyoplysine |
| abstract | The present invention relates to (1) a process for preparing a cyclopentadienyl derivative of sodium by reacting a cyclopentadiene and sodium amide in a N, N-dimethylformamide solvent, reacting the sodium cyclopentadienylide with an isopropylating agent, (2) subjecting the mixture of isopropylcyclopentadiene to reaction with dichloro ketene to obtain 7,7-dichlorobiscyclo [3.2.0] -hept-2-en-6 2-ene-6-one derivative obtained in the step (1) is subjected to solvolysis in the presence of a basic condition to obtain a mixture of the 7,7-dichlorobicyclo [3.2.0] And a third step of separating? -Toyoplysine from the crude product by crystallization. According to this method,? -Toyoplycine, which is useful as an intermediate of medicine, can be obtained inexpensively and easily and in a good yield. |
