total synthesis featuring a cross metathesis and a macrolactamization on a solid support followed by a ring-closingmetathesis in solution. Via this route the title compound was obtained in an overall yield of 7% (85% on average for 16 reaction steps). In the second approach, the linear precursor peptide was subjected to ring-closingmetathesis and the bicyclic peptide with the correct side chain connectivity
