A biomimetic approach has been investigated and developed for the total synthesis of azonazine, an unusual marine natural cyclopeptide containing a rigid transannular 10-membered ring. A hypervalent iodine-mediated direct oxidative cyclization was successfully developed and applied to construct the highly strained core, which was the key step in the first total synthesis of ent-(-)-azonazine. Based on the physical evidences of synthesized diastereomer and enantiomer of azonazine, both the relative and absolute configurations of the natural product were revised. Two fluorinated azonazine derivatives were also synthesized in short convenient steps utilizing the same intermediate in this work. The established total synthesis opens a potential opportunity to study the structure-activity relationship of natural azonazine.

Cryptophycin A, a cyclic depsipeptide isolated from the blue-green alga (cyanobacterium) Nostoc sp.GSV 224, has shown excellent activity against solid tumors implanted in mice. The benzylic epoxide, which was shown to be very important for biological activity, is also fairly unstable under both acidic and alkaline conditions. The high doses needed to observe in vivo activity might be a result of this instability. In order to solve this problem while preserving the electrophilic character of the benzylic position, enones 1 and 2 have been proposed as promising analogs of the natural product, and a convergent total synthesis of these compounds is described. In addition, the same strategy was used to prepare Cryptophycins A,B, C, and D.

In search of a connection between prebiotic peptide chemistry and lipid compartments, the reaction of a 5(4H)-oxazolone with leucinamide was extensively explored under buffered aqueous conditions, where diverse amphiphiles and surfactants could form supramolecular assemblies. Significant increases in yield and changes in stereoselectivity were observed when fatty acids exceeded their critical aggregation concentration, self-assembling into vesicles in particular. This effect does not take place below the fatty acid solubility limit, or when other anionic amphiphiles/surfactants are used. Data from fluorimetric and Langmuir trough assays, complementary to the main HPLC results reported here, demonstrate that the dipeptide product co-localizes with fatty acid bilayers and monolayers. Additional experiments in organic solvents suggest that acid-base catalysis operates at the water-aggregate interface, linked to the continuous proton exchange dynamics that fatty acids undergo at pH values around their effective pKa. These simple amphiphiles could therefore play a dual role as enhancers of peptide chemistry under prebiotic conditions, providing soft and hydrophobic organic domains through self-assembly and actively inducing catalysis at their interface with the aqueous environment. Our results support a systems chemistry approach to life’s origin.
