An asymmetric oxidative C–N bond-forming reaction is developed using a chiral diiodospirobiindane derivative as the catalyst and mCPBA as a terminal oxidant. The protocol is based on an asymmetricdesymmetrization strategy and affords lactams or spirolactams according to the different substituents on the substrates. The products are obtained in good yields and moderate to high enantioselectivities.
Novel amino acid derivatives useful as a therapeutic agent are disclosed. These amino acid derivatives and the pharmaceutically acceptable salts thereof have a human renin inhibitory effect when administered orally and are useful for treatment of hypertension, especially renin-associated hypertension.
