A novel three-component reaction of anilines, formaldehyde and dimedone: simple synthesis of spirosubstituted piperidines
摘要:
A three-component condensation of anilines with dimedone and formaldehyde leads to the formation of 3,5-dispirosubstituted piperidines. This simple reaction can serve as a convenient source of 3,5-disubstituted piperidines as well as polyfunctional 3-spirofused piperidines. (c) 2008 Elsevier Ltd. All rights reserved.
