چکیده
4-Nitrobenzylidenedimethylsulfurane 4-Nitrobenzylidenedimethylsulfurane, a semi-stabilized sulfonium ylide has been generated by the attack of methylsulfinyl carbanion in dimethyl sulfoxide and reacted with a series of substituted benzaldehydes, furfural and benzylideneacetophenone to afford <mns-l,2-disubstituted epoxides in fair to good yields. The structural assignments of the products are based on IR and NMR spectral evidences.

Rapid Asymmetric Synthesis of Disubstituted Allenes by Coupling of Flow‐Generated Diazo Compounds and Propargylated Amines
We report herein the asymmetric coupling of flow-generated unstabilized diazo compounds and propargylated amine derivatives, using a new pyridinebis(imidazoline) ligand, a copper catalyst and base. The reaction proceeds rapidly, generating chiral allenes in 10-20 minutes with high enantioselectivity (89-98 % de/ee), moderate yields and a wide functional group tolerance.
متن کاملDiastereoselective synthesis of 2,3,6-trisubstituted tetrahydropyran-4-ones via Prins cyclizations of enecarbamates: a formal synthesis of (+)-ratjadone A.
Enecarbamates are shown to be excellent terminating groups for Prins cyclizations. A noteworthy feature of this methodology is the easy, stereoselective construction of the cyclization precursors by alkylation of metalated (E)-enecarbamates with epoxides. The stereochemistry of the resultant trisubstituted (E)-enecarbamates is then transferred with high fidelity to afford the frequently observe...
متن کاملEfficient, stereoselective synthesis of trans-2,5-disubstituted morpholines.
[reaction: see text] Enantio- and diastereoselective syntheses of trans-2,5-disubstituted morpholine derivatives are described. The routes are initiated by the reaction of enantiopure epoxides (2) with amino alcohols (3) and address the problem of regioselective hydroxyl activation-ring closure of the resulting amino diol adducts for (amino alcohol-derived) alkyl substituents of different steri...
متن کاملEnantioselective synthesis of 2,2-disubstituted terminal epoxides via catalytic asymmetric Corey-Chaykovsky epoxidation of ketones.
Catalytic asymmetric Corey-Chaykovsky epoxidation of various ketones with dimethyloxosulfonium methylide using a heterobimetallic La-Li(3)-BINOL complex (LLB) is described. The reaction proceeded smoothly at room temperature in the presence of achiral phosphine oxide additives, and 2,2-disubstituted terminal epoxides were obtained in high enantioselectivity (97%-91% ee) and yield ( > 99%-88%) f...
