An improved synthesis of the scyphostatin side-chain
摘要:
A formal synthesis of the lipophilic side-chain of scyphostatin has been achieved using a convergent synthesis, in 16% yield over,six steps. This synthesis involves enzymatic desymmetrisation of a meso-diol, resolution of 2-methylbutan-1-ol, stereoselective hydrozirconation of a volatile acetylene and a Negishi-style cross coupling.
