An efficient diastereoselective synthesis of substituted piperidines is accomplished by using catalytic amount of FeCl3·6H2O via intramolecular aza-Michael addition of carbamate on alkylidene β-keto (L)-menthyl esters in a very short time.

FeCl 3 ·6H 2 O催化(L)-薄荷基4-氧代-2-芳基哌啶-3-羧酸酯的非对映选择性合成
通过在很短的时间内通过催化量的FeCl 3 ·6H 2 O分子内氨基甲酸酯在亚烷基β-酮(L)-薄荷基酯上的氨基甲酸酯加成反应,可以实现取代哌啶的高效非对映选择性合成。
