Synthesis of a Cyclic Analogue of Tuv N-Methyl Tubulysin

초록/요약

Tubulysins are the most potent antimitotic agents known so far. We are interested in the conformational effect of tubulysin and herein we report the design and synthesis of a conformationally rigid cyclic analogue of Tuv N-methyl tubulysin. A conformationally rigid tetrahydropyran moiety was incorporated into the Tuv fragment via enantioselective hetero Diels-Alder reaction to prevent the rotation of the Tuv chain. The following diastereoselective reductive amination yielded the (4-methylamino)tetrahydropyranyl Tuv fragment, which was coupled to d-Mep-l-Ile dipeptide fragment and Tup fragment sequentially.
