Li, Shuangshuang published the artcilePractical allylation with unactivated allylic alcohols under mild conditions, Recommanded Product: 3-Acetyldihydrofuran-2(3H)-one, the publication is Organic Chemistry Frontiers (2021), 8(13), 3354-3359, database is CAplus.
A practical palladium/calcium catalytic system was developed for dehydrative allylation with unactivated allylic alcs. EtOH solvent with a H2O additive was identified as powerful medium to accelerate proton transfer. This catalytic system and environmentally benign medium enabled a variety of soft carbonic nucleophiles and allylic alcs. to react smoothly at room temperature with water as the only byproduct. A wide spectrum of allylic compounds bearing a variety of functional groups I [R = Me, CN, CO2Et, etc.; R1 = CO2Me, CO2Et; R2 = CN, NO2, CO2Me, CO2Et; R3 = H, Me; R4 = H, Me; R5 = Ph, 2-FC6H4, 2-thienyl, etc.] could be obtained with high to excellent yields.
