The family of aldisines, isolated from marine sponges, presents a great interest not only for the synthetic pathways but also for biological aspects. To complete this work, various syntheses of indolic analogues and derivatives of this family were developed. A bibliographic study showing the most known compounds of the aldisines’ family and their syntheses will be reported in a first part. Then, in a second part, a general and efficicent synthesis of structural analogues of latonduine A was carried out via a palladium-catalysed intramolecular reaction of arylation. Several of these final compounds show a sub-micromolar antiproliferative activity on various tumoral human cell lines. The third part of this work reports the preparation of new 4-hydroxy-2,3,4,5-tetrahydro[1,4]diazepino[1,2-a]indol-1-ones (derivated from the aldisine) from alkyl indole-2-carboxylates. These compounds show a significant activity on Cyclin-Dependent Kinases (CDKs) which is one of the main therapeutic targets for the cancer treatment since the last decade. Finally, a non-classical route to 2,3-diiodoindoles from indole-2-carboxylic acids is described in a fourth part.
