Abstract
Photochemical transformations are powerful tools for organic synthesis. In the contemporary context, marked by the importance of green chemistry principles and sustainable development, the use of light to carry out selective reactions offers considerable advantages. Among the most useful synthetic reactions are photo-cyclizations, which create 4-membered cyclic skeletons. In this presentation, we will describe two facets of the photo-cyclizations we are developing in our laboratory.
In the first part, we will describe some applications of 2+2 photo-cycloadditions for the efficient synthesis of cyclobutanes, azetidines and oxetanes with various functionalities; these compounds are targeted primarily as monomers for the construction of regularly structured oligomers, called foldamers.
