Texto completo da fonteBenzocyclobutenes (BCBs) derivatives are of significant interest due to the cooperative effects between the thermodynamic stability coming from the aromatic ring and the high reactivity of the strained cyclobutene moiety. In this regard, BCBs have been used as an original building block for the synthesis of natural products and also as precursors for the development of polymers. On the other hand, small rings represent a valuable three-atoms building element in the search to reach molecular complexity in an atom economical manner and often participate in fascinating chemical transformations. This release of ring tension usually allows for a scalable, rapid and controlled synthetic access to the expected target molecules. In this context, a new class of donor-acceptor cyclopropane (DAC) has recently been developed in our laboratory combining a silyl protected cyclopropanol with an α,β-unsaturated ester. Gratifyingly, the latter delivered the corresponding highly functionalized benzocyclobutenes in good yields. Experimental investigations demonstrated that depending on the substitutions of the silyl protected cyclopropanol (donor part), a one-step or two-steps approach had to be adopted. In this way, a library of BCB with alkyl- or aryl- substituent on the cyclobutene ring have been synthesised. Mechanistic studies demonstrated experimentally the total regioselectivity observed on the substituted BCB depending on the diastereochemistry of the DAC. Finally, the synthesis of taylor-made monomers has been also explored. Typically, the introduction of an alkoxy or amino group on the four-membered ring has been envisaged thanks to a post-functionalisation approach

Texto completo da fonteIn the quest for new therapeutic candidates, the description of novel synthetic approaches to access to increasingly complex carbon systems remains a daunting challenge. In order to increase the structural of such scaffolds, it is necessary to overcome the encountered difficulties by developing new straightforward an efficient tools. In this context, this work has mainly focused on the access of structurally defined carbon cycles by ring expansion reactions via the use of polarized compounds. The first part of this study has been devoted to the Tiffeneau-Demjanov ring expansion reaction using ethyl α-chlorodiazoacetate. This approach allowed us to access highly versatile cyclic keto esters displaying a tetrasubstitued carbon center bearing a chlorine atom. The next topic of this study has been focused on the development of a (5 + 3) cycloaddition reaction between two polarized cyclopropane entities. This methodology led to the description of a novel reactivity of donor-acceptor cyclopropanes compounds to form α,β,γ-trisubstituted lactones under a BrØnsted acid activation. In order to gain mechanistic insights, a theoretical study has also been conducted which led us to rationalize the mechanism and the selectivity of this transformation. The last part described the reactivity of a underexplored class of molecule, the vinylbiscyclopropanes. These compound, can lead to the benzocyclobutene family and to the 8 membered-ring compounds through rearrangement or formal [3.3] sigmatropic rearrangement reaction. This last class of compound is still under study and should allow rapid access to diverse cyclic structures
