γ-regioselective-alkylation reaction which is catalyzed by a chiraltertiaryamine ((DHQ)2PHAL) and takes advantage of isatin-derived Morita-Baylis-Hillman carbonates and CF3-contained ketoimines, delivered chiral α-trifluoromethylamine derivatives and incorporated an oxindole motif in yields of 65–98%, diastereoselectivities (>20:1 in most cases) and enantioselectivities of 73–99%. The subsequent deprotection
Catalytic Asymmetric Synthesis of Vicinally Bis(trifluoromethyl)-Substituted Molecules via Normal [3 + 2] Cycloaddition of <i>N</i>-2,2,2-Trifluoroethyl Benzothiophene Ketimines and β-Trifluoromethyl Enones
An organocatalytic asymmetric [3 + 2] cycloaddition of β-trifluoromethyl enones with 3-(N-2,2,2-trifluoroethyl) benzothiophene ketimines and 2-(N-2,2,2-trifluoroethyl) benzothiophene ketimines was described for the first time. A wide spectrum of vicinally bis(trifluoromethyl)-substituted spiro pyrrolidine-benzothiophenones were obtained with excellent stereocontrol (all cases >20:1 dr and up to 99%
描述了β-三氟甲基烯酮与 3-( N -2,2,2-三氟乙基)苯并噻吩酮亚胺和 2-( N -2,2,2-三氟乙基)苯并噻吩酮亚胺的有机催化不对称[3 + 2]环加成反应第一次。获得了一系列邻位双(三氟甲基)取代的螺吡咯烷苯并噻吩酮,具有出色的立体控制性(所有情况> 20:1 dr 和高达 99% ee)。这项工作的亮点是在构建具有邻位双(三氟甲基)取代的吡咯烷部分和四个连续立体中心的螺环苯并噻吩酮衍生物方面具有极高的效率。
Acid‐Controlled Regional Diverse Synthesis of CF<sub>3</sub>‐Containing Ketoimines and Application in the Construction of Bispiro[oxindole‐pyrrolidine‐benzothiophenone]s
Here described an acid‐controlled regional diverse synthesized process of CF3‐containing ketoimines by the condensation of benzo[b]thiophene‐2,3‐dione and 2,2,2‐trifluoroethlamine. The imines obtained at either the 2‐position or 3‐position can be further used as substrates in asymmetric organocatalyzed [3+2]‐cycloaddition reactions, leading to a library of regiodiverse bispiro‐compounds with 85–96 % yield and 65–99 % ee.
