One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Product Details of 1193-54-0, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 1193-54-0, Name is 3,4-Dichloro-1H-pyrrole-2,5-dione, molecular formula is C4HCl2NO2
Intramolecular photocycloaddition of N-alkenyl substituted maleimides: A potential tool for the rapid construction of perhydroazaazulene alkaloids
UV irradiation of a number of N-alkenyl-substituted maleimide derivatives leads to the formation of complex perhydroazaazulenes in excellent yields. The overall process can be considered as a formal intramolecular [5+2] cycloaddition. Substrates were prepared by Mitsunobu coupling of the appropriate alkenols with various maleimides. Methyl substitution of the alkenyl side chain gave the cycloadducts 13a-g in good yields, with moderate to high stereoselectivity being observed for 13e and 13g, respectively. Use of cyclic alkene side chains led to the formation of tri- and tetracyclic products with high degrees of stereoselectivity in most cases. Some of the polycyclic ring systems that were prepared constitute the core skeleton of a number of complex alkaloids. The substrate 29 underwent an unexpected [2+2] photocyclo-addition to yield the unusual cyclobutane 31.
