The research focuses on the synthesis of 1-methoxy-1-(phenylthio)cyclopropanes from olefins via the Pummerer rearrangement. The purpose of this study was to develop a versatile and mild method for the preparation of cyclobutanones, which are valuable precursors in the synthesis of higher ring systems, acyclic fragments, and natural products. The researchers successfully modified the Pummerer reaction to achieve high yields of the title compounds through a series of steps involving carbene addition, oxidation, and methylation. Key chemicals used in the process include olefins, phenylthiocarbene, m-chloroperbenzoic acid, trimethyloxonium fluoroborate, and sodium methoxide in methanol. The study concluded that the Pummerer rearrangement of methoxysulfonium salts involving cyclopropanes is a highly stereoselective method for preparing fused bicyclic cyclopropanes, which are useful precursors of fused cyclobutanones.
The research focuses on the intramolecular C-H insertion reactions of (cyclopentadienyl)dicarbonyliron carbene complexes, which are well-known species in transition metal chemistry. The purpose of the study was to explore the reactivity of these iron complexes, particularly in alkylidene transfer reactions with alkenes to form cyclopropanes, as well as their potential in cationic olefinic cyclization and intramolecular C-H insertion reactions. The researchers reported the preparation and use of a stable thiocarbene complex, Cp(CO)2Fe+=CHSPh PF6 (1), as a reagent for incorporating carbene centers into various organic systems through carbanionic addition reactions. Key chemicals used in the process include 2-cyclohexenone, (2-phenylethyl)magnesium bromide, tri-methylsilyl chloride, and trimethyloxonium tetrafluoroborate. The conclusions drawn from the study indicate that these iron carbene complexes can undergo intramolecular C-H insertion reactions, leading to the formation of cyclopentane-fused products, and that the reactions show stereoselectivity which may be explained by the conformation of the intermediate carbene complexes. The study also highlights the potential of these iron-based reactions in synthetic strategy, noting their complementarity to rhodium-catalyzed reactions and the ease with which complex substrates can be obtained from simple starting materials.
