Enantioselective synthesis of epoxides by α-deprotonation - Electrophile trapping of achiral epoxides

Enantioselective α-deprotonation of achiral epoxides 1, 21, and 26 using organolithiums in the presence of (-)-sparteine 2 and subsequent electrophile trapping gives access to enantioenriched trisubstituted epoxides 9-17, 22, 23, 27 and 28 (in up to 86% ee).

Simple meso-epoxides can be asymmetrically functionalized: Ligand-assisted direct hydrogen-lithium exchange allows the generation of destabilized oxiranyl lithium species and their subsequent trapping by a wide array of electrophiles (see scheme; E = grou

Photocatalytic Oxygenation of Selected Cycloalkenes in Aqueous Solutions Induced by Water-Soluble Metal Porphyrin Complexes

Water-soluble manganese(III) as well as iron(III) porphyrinates are introduced as light-sensitive precursor compounds for the photocatalytic activation of dioxygen in aqueous solutions.It is shown that in the presence of α-pinene (4) and the further cycloalkenes 11-13 photocatalytic oxygenation reactions occur.The dependence of the selectivity of the oxygen transfer to the olefin on both the presence of water and the variation of the substrate-to-catalyst ratio is discussed.The catalyst may be conveniently separated from the substrates/products by using aqueous solvent systems. - Key Words: Photooxygenation / Dioxygen activation / Metallporphyrins / Epoxidation
