Both enantiomers of two new chiral modifiers (naphthyl- and anthryl-[1,2,5,6-tetrahydro-pyridinyl] methanols, 4H and 5H ) are obtained for the first time from inexpensive d -mannitol in 10 easy steps. Until now erythro - 4H is the only synthetic chir

It is shown that catalytic heterogeneous hydrogenation over Ru/Al2O3 of mono- and di-substituted phenols (1–4) works and provides mixtures of the two or four possible isomers. Although cis and all-cis isomers (corresponding to all-syn H2 additions)

A route toward the synthesis of the erythro isomer of (9-anthryl)(2-piperidyl)methanol is presented as well as resolution and assignment of the structure (through NMR). The use of both the erythro and threo enantiopure isomers of this new amino alcoh

Amberlyst 15 is an efficient catalyst for the reaction of aryl-substituted oxiranes with acetone to prepare 2,2-dimethyl-1,3-dioxolanes in high yields. trans-2,3-Diaryloxiranes afford trans-acetonides enantiospecifically at room temperature, and the

Heterogeneous hydrogenations of 1-naphthol and 2-naphthol over Ru/Al 2 O 3 -9001 (from Engelhard) are presented. It was found that 1-naphthol provides almost exclusively (98–100%) the cis -decalols (OH equatorial and axial) while the 2-naphthol lea

Unknown diaryl (1-3) and alkyl-phenyl (4, 5) N-tosyl aziridines have been successfully synthesized from pure (R,R,R,S(S))-(-)-sulfonium salt derived from Eliel's oxathiane, tosylimines 11a-f, and using a phosphazene base (EtP(2)) to generate the ylid
