| titleOfInvention | A kind of new synthetic method of Carfentanil |
| abstract | The invention belongs to organic synthesis fields, and in particular to a kind of synthetic method of Carfentanil synthesis.The synthetic method is using N-Boc protecting group piperidones as raw material, and by Bargellini reaction, N- is acylated, methylation, be deprotected, N- is alkylated 5 steps and has obtained target product Carfentanil.The present invention uses Carfentanil new synthetic method, avoids the use of extremely toxic substance potassium cyanide, and environmental-friendly, yield is higher, and synthetic route is relatively easy, can satisfy the requirement of Modern high throughput, inexpensive synthesis theory. |
