Synthesis of Cyclohexa-1,3-dienamines by Formal [3+3] Cycloaddition
摘要:
Formal [3+3] cycloadditions of beta-carboxymethylenamino esters with acrolein derivatives give a range of cyclohexa-2,6-dicarboxymethyl-1,3-dienamines that are potential acceptordonor-acceptor systems.
An easy, two-step approach to various 5-carboxymethyl-2(5H)-furanones is described. A detailed study of the reaction of β-carboxymethyl enamino esters with N-bromosuccinimide is presented.
