Synthesis of the cyclic heptapeptide core of callipeltin A
[article]
2022
Preserved Fulltext
Macrolactonisation of a novel heptapeptide precursor with PyAOP proved to be an excellent method for preparation of the cyclic depsipeptide core of callipeltin A. The individual building blocks were obtained in high yield and selectivity and successive coupling allowed for the straightforward preparation of the linear heptapeptide from tyrosine 6 in 27% over 12 steps.
