An efficient route to 4-substituted quinazolines by arylation or alkylation of quinazolinones under mild conditions is described. 4-Tosyloxyquinazolines were obtained through the reaction of quinazolinones and p-methylbenzenesulfonyl chloride in the presence of K2CO3. The cross-coupling reaction of 4-tosyloxyquinazolines with organoindium reagents, carried out in tetrahydrofuran, catalyzed by Pd2(dba)3/ (2-furyl)3P led to the formation of 4-functionalized quinazolines in good to excellent yields. Higher yields were obtained by the one-pot reaction of quinazolinone, p-methylbenzenesulfonyl chloride, Pd2(dba)3-/(2-furyl)3P, and organoindium reagent. These methods using organoindium compounds as coupling partners provided an efficient route to 4-(hetero)aryl/alkylquinazolines, especially 4-substituted quinazolines bearing a halogen scaffold.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C51H42O3Pd2, you can also check out more blogs about52409-22-0
