Amide-Group-Directed Protonolysis of Cyclopropane: An Approach to 2,2-Disubstituted Pyrrolidines

Regioselective protonolytic C-C bond cleavage of acylated aminomethyl cyclopropanes can be achieved using trifluoroacetic acid. The intermediate tertiary carbenium ion undergoes an intramolecular amination to give 2,2-substituted pyrrolidines. The strength of the acid and the amine substituent are important factors to achieve high regioselectivity, suggesting intramolecular proton transfer from the protonated amide function. Preliminary mechanistic studies revealed that cyclopropane cleavage proceeds with retention of configuration at the carbon to which the proton is attached. This observation is consistent with the "edge" protonation trajectory of the C-C bond.

Nickel-Catalyzed Reductive Carboxylation of Cyclopropyl Motifs with Carbon Dioxide

A nickel-catalyzed reductive carboxylation technique for the synthesis of cyclopropanecarboxylic acids has been developed. This user-friendly and mild transformation operates at atmospheric pressure of carbon dioxide and utilizes either organic halides or alkene precursors, thus representing the first example of catalytic reductive carboxylation of secondary counterparts lacking adjacent π-components.

Synthesis of 1-arylpiperazyl-2-phenylcyclopropanes designed as antidopaminergic agents: Cyclopropane-based conformationally restricted analogs of haloperidol

A series of the cyclopropane-based conformationally restricted analogs of haloperidol were designed as potential antidopaminergic agents and were effectively synthesized using highly stereoselective Grignard reaction with tert-butanesulfinyl imines as the key step. Pharmacological evaluation of the compounds showed that the conformational restriction method can effectively work for improving the pharmacological selectivity of a parent compound and also for investigating the bioactive conformation.
