The synthesis of a new series of 3-alkoxy-5-hydroxy-5-trifluoromethyl pyrrolidin-2-ones 2a-h from the reaction of 1,1,1-trifluoro-4-alkoxyalk-3-en-2-ones 1a-h of the general formula F3CC(O)C(R2)=C(R1)OR, where: R = Me, Et, -(CH2)2-, -(CH2)3-; R1 = H, Me, Ph, p-Me-Ph, p-F-Ph; and R2 = H, Me, -(CH2)2-, -(CH2)3- with sodium cyanide in hydro-alcoholic medium is reported.
报道了在含氢酒精介质中,通过1,1,1-三氟-4-烷氧基-3-烯-2-酮1a-h(通式为F3CC(O)C(R2)=C(R1)OR,其中:R = Me、Et、-(CH2)2-、-(CH2)3-;R1 = H、Me、Ph、p-Me-Ph、p-F-Ph;R2 = H、Me、-(CH2)2-、-(CH2)3-)与氰化钠的反应,合成一系列新的3-烷氧基-5-羟基-5-三氟甲基吡咯烷-2-酮2a-h。
