Salvianolic acid A analogue and application thereof as antioxidant
The invention provides a novel salvianolic acid A analogue with antioxidant activity. The ROS can be directly or indirectly eliminated by up-regulating expression of CAT, SOD and like antioxidase andincreasing the production of the non-enzymatic antioxida

Memory of chirality of tertiary aromatic amide: Application to the asymmetric synthesis of (S)-α-methylDOPA
We describe an original asymmetric synthesis of (S)-α-methylDOPA proceeding by the concept of memory of chirality, the only source of chirality being the starting d-alanine. The initial chirality of the amino acid is temporarily transferred to a dynamic axial chirality of a tertiary aromatic amide. The (S)-α-methylDOPA hydrochloride is obtained after four steps with 98% ee.
