                                Substituent effect of 4-and 5-substituted 2-aryl-methylideneindane-1,3-diones on formation of 5-oxo-1H-4,5-dihydroindeno[1,2-b]pyridines
                             
                            
                                摘要:
                                The ratio of dihydroindenopyridine regioisomers formed from ethyl beta-amino-crotonate and 4- or 5-monosubstituted 2-arylideneindane-1,3-dione depends on the total electronic and steric effects of the indanedione substituents.
