SYNTHESIS OF DERIVATIVES OF 1,2,6-TRISUBSTITUTED-4-PIPERIDONES

Robinson-Schopf cyclisation was used to prepare several 1,2,6-trisubstituted-4-piperidones. 1,2,6-trimethyl-4-piperidone, tricyclic ketones 2 and 3 derivatives of coccinelline. In the case of 1,2,6-trimethyl-4-piperidone, a mixture of the trans and cis compounds 4 and 1 was obtained. The pure cis co...

Summary:Robinson-Schopf cyclisation was used to prepare several 1,2,6-trisubstituted-4-piperidones. 1,2,6-trimethyl-4-piperidone, tricyclic ketones 2 and 3 derivatives of coccinelline. In the case of 1,2,6-trimethyl-4-piperidone, a mixture of the trans and cis compounds 4 and 1 was obtained. The pure cis compound was prepared by another route.
