Scope and Limitations in Palladium-Catalyzed Substitution Reactions of Unsaturated Fused Lactones. -A range of Ξ±-substituted lactones of type (I) are prepared in order to study how electronic and steric factors influence the rate of the substitution reaction. The rates are found to increase with in
The reactions of iodouracils having a formamidine or acetamidine moiety 1 with various acetylenes 2 in DMF at 120 C using potassium carbonate and a catalytic amount of palladium acetate gave a mixture of pyrido [2,3-d]pyrimidine derivatives in good to high yields. Addition of lithium chloride to the
