and coupling of organic radical species, the alkoxycarbonylradical remains underexplored relative to other carbon-containing radical species. Drawing inspiration from new strategies for generating acyl radical equivalents utilizing dual N-heterocyclic carbene catalysis and photocatalysis, we have prepared dimethylimidazolium esters that can function as an alkoxycarbonylradical surrogate under photocatalytic

Disclosed are process steps and novel processes for producing chromane compositions enriched in at least one (2R or 2S) enantiomer, preferably chroman-2-yl carboxylic acid compounds and chroman-2-yl carboxylic acid esters which are intermediates for producing platelet aggregation inhibitors and/or are themselves potent platelet aggregation inhibitors. Further disclosed are enzymatic processes for resolving chiral intermediates or final products to provide desired enantiomers.
Intramolecular photochemical [2 + 1]-cycloadditions of nucleophilic siloxy carbenes

singlet nucleophiliccarbenes undergo rapid [2 + 1]-cycloaddition with tethered olefins to afford unique bicyclo[3.1.0]hexane and bicyclo[4.1.0]heptane scaffolds. This cyclopropanation process requires only visible light irradiation to proceed, circumventing the use of exogenous (photo)catalysts, sensitisers or additives and showcases a vastly underexplored mode of reactivity for nucleophilic carbenes

Disclosed are processes for producing a (2S) or (2R) 4-oxo-chroman-2-yl acyl compounds and chroman-2-yl acyl compounds, esters or amides thereof as well as derivatives thereof. Such processes may involve chiral synthesis or achiral synthesis, preferably coupled with a resolution procedure. Such compounds, particularly (2S) or (2R) acetic acid esters, are useful intermedates for producing platelet aggregation inhibitors and/or are themselves potent platelet aggregation inhibitors. Further disclosed are processes for making derivatives of such substantially pure, or enhanced compositions of single (2R) or (2S) enantiomer intermediates or processes for producing final products or salts from such desired enantiomers.
