Dessertation describes of the first reported syntheses of the natural products lairdinol A and depsilairdin. The key steps in the synthesis of depsilairdin were N-terminal extension (C←N) of the protected proline fragment, hydrolysis of the tetrapeptide fragment with free secondary alcohol in the proline moiety and esterification of the HOBt ester of tetrapeptide fragment with the bromomagnesium alkoxide of lairdinol A.
