摘要:
A novel convenient approach for the synthesis of densely functionalized pyrano[3,4-c]pyrrole derivatives was developed. Cascade transformation of the simple adducts of tetracyanoethylene (TCNE) and ketones (4-oxoalkane-1,1,2,2-tetracarbonitriles) in the presence of aldehyde under the action of acetic acid led to the diastereoselective formation of targeted pyrano[3,4-c]pyrroles. The reaction pathway was thoroughly investigated, and proposed intermediates consistent with experiment. were shown to be
