A series of thiophene mono (oxazoline) N,O-ligands with three sites of diversity were synthesized concisely in two steps from the corresponding thiophene carbonitriles. These ligands were applied to the enantioselective phenyl transfer reaction of aldehydes, resulting in the corresponding chiral diaryl methanol products with excellent yields and moderate to good enantioselectivities.
从相应的噻吩腈中分两步简要合成了具有三个多样性位点的一系列噻吩单(恶唑啉)N,O-配体。将这些配体用于醛的对映选择性苯基转移反应,得到具有优异收率和中等至良好对映选择性的相应的手性二芳基甲醇产物。
