  Microwave-Assisted Synthesis ofN-Heterocycles and Their Evaluation Using an Acetylcholinesterase Immobilized Capillary Reactor

  摘要：

  Os etenoditioacetais polarizados sao conhecidos como importantes intermediarios em muitos processos de sintese. Neste trabalho, reporta-se a anelacao livre de metal de transicao de 1,1-bis(tiometil)-2-nitroetileno com hidroxilalquilaminas e alquildiaminas. Esta metodologia permite a sintese direta de N-heterociclos tais como imidazolidinas, oxazolidinas e benzoxazis sob irradiaao de micro-ondas. Estes compostos foram avaliados como inibidores da acetilcolinesterase usando um reator capilar contendo a enzima imobilizada acoplado a um espectrmetro de massas.Polarized ketene dithioketals have been recognized as useful building blocks in many synthetic operations. In this work, a transition-metal-free annulations of 1,1-bis(thiomethyl)-2-nitroethylene with hydroxylalkylamines or alkyldiamines have been reported. This methodology provides a directed approach to N-heterocycles, e.g., imidazolidines, oxazolidines and benzoxazoles under microwave conditions. These compounds were evaluated as acetylcholinesterase inhibitors by using an enzyme immobilized capillary reactor-tandem mass spectrometry.
