| A new efficient method for the synthesis of scyphostatin and its analogs is presented. Starting from 2,4-dihydroxy benzylaldehyde, an advanced tyrosine analog enantioselectively prepared in 6 steps. Distereoselective cyclization of the tyrosine analog with PIFA followed by selective epoxidization give the core of scyphostatin. A sorbic acid derivative is prepared. |
