2,3,7-Trisubstituted indolizines were obtained from E- or Z-2-enynyl-4-substituted pyridines. The mechanistic pathway involves a base-catalyzed double-bond isomerization, if the E-isomer is the starting material, followed by a concerted pseudocoarctate cyclization.
从E-或Z -2-炔基-4-取代的吡啶获得2,3,7-三取代的吲哚嗪。如果E-异构体是起始材料,则该机理途径涉及碱催化的双键异构化,然后是协同的伪缩合物环化。
