Kamitanaka, Tohru published the artcile[3+2] Coupling of Quinone Monoacetals with Vinyl Ethers Effected by Tetrabutylammonium Triflate: Regiocontrolled Synthesis of 2-Oxygenated Dihydrobenzofurans, Name: 1,3-Dimethoxybenzene, the main research area is dihydrobenzofuran preparation diastereoselective regioselective; quinone monoacetal vinyl ether coupling tetrabutylammonium triflate catalyst.
The synthesis of 2-oxygenated dihydrobenzofurans I (R = H, Me, t-Bu, OMe, NHAc; R1 = H, Me, t-Bu; R2 = Me, Et; R3 = H, OMe; X = -CH2-, -O-; n = 0, 1), II (R4 = Et, i-Pr; R5 = H, Me) involving the [3+2] coupling of quinone monoacetals III with vinyl ethers IV has been realized by tetrabutylammonium triflate catalysis. The reaction involves a new activation method of the acetal moiety in quinone monoacetals III under acid-free conditions affording the highly oxygenated dihydrobenzofurans I, II. This new activation mode was achieved by using the triflate anion catalyst for stabilization of the highly reactive cationic intermediate.
