An original oxidative ring contraction of easily accessible cyclobutene derivatives for the selective formation of cyclopropylketones (CPKs) under atmospheric conditions is reported. Comprehensive mechanistic studies are proposed to support this novel, yet unusual, rearrangement. Insights into the mechanism ultimately led to simplification and generalization of the ring contraction of cyclobutenes using mCPBA as an oxidant. This unique and functional group tolerant transformation proceeds under mild conditions at room temperature, providing access to a new library of polyfunctionalized motifs. With CPKs being attractive and privileged pharmacophores, the elaboration of such a simple and straightforward strategy represents a highly valuable tool for drug discovery and medicinal chemistry. Additionally, the described method was employed to generate a pool of bioactive substances and key precursors in a minimum number of steps.

The most common CF mutation, F508del, impairs the processing and gating of CFTR protein. This deletion results in the improper folding of the protein and its degradation before it reaches the plasma membrane of epithelial cells. Present correctors, like VX809 only induce a partial rescue of the mutant protein. Our previous studies reported a class of compounds, called aminoarylthiazoles (AATs), featuring an interesting activity as correctors. Some of them show additive effect with VX809 indicating a different mechanism of action. In an attempt to construct more interesting molecules, it was thought to generate chemically hybrid compounds, blending a portion of VX809 merged to the thiazole scaffold. This approach was guided by the development of QSAR analyses, which were performed based on the F508del correctors so far disclosed in the literature. This strategy was aimed at exploring the key requirements turning in the corrector ability of the collected derivatives and allowed us to derive a predictive model guiding for the synthesis of novel hybrids as promising correctors. The new molecules were tested in functional and biochemical assays on bronchial CFBE41o-cells expressing F508del-CFTR showing a promising corrector activity.

The invention relates to the field of medicinal chemical synthesis, and discloses a method for preparing benzo[1,3-d] dioxole and an intermediate of benzo[1,3-d] dioxole. The method comprises the following steps: performing three steps of reactions of chloro-substitution, fluorination and deprotection on a compound of formula (4) as shown in the specification so as to prepare a compound of formula (1) as shown in the specification, and in the formulae, R is a carboxyl protection group. By adopting the method, the problems that in the prior art, the yield of benzo[1,3-d] dioxole is low and the reaction operation is not safe can be solved, the compound of the formula (4) is adopted as a raw material which is directly introduced into a three-membered ring structure, so that a dangerous sodium cyanide reagent is not used, and moreover, a reaction route is shortened, the overall yield of the reaction can be greatly increased, and the method is applicable to industrial production.
