A new convenient method for the synthesis of chiral C3-synthons
摘要:
Routes are described for the facile preparation of protected optically pure D- and L-glyceric acid (1a,b; 2a,b) starting from D-mannitol, D-isoascorbic acid and L-ascorbic acid. The key step is a ruthenium catalyzed oxidative cleavage of the vicinal diols 4a,b or the alpha-hydroxy acids 7a,b; 10a,b.
