Popis: | A method for enantioselective desymmetrization of N-Ac and N-Boc-FTY720 by nonenzymatic asymmetric acylation was developed. Effective enantioselective monobenzoylation using benzoyl chloride in the presence of the tetraphenylbisoxazoline (L2)-CuCl2 complex gave the desired products 3a and 3b in 52-62% yield with 64% ee. |
