HYDRŒCIA NELITA, STRECKER

Asymmetric strecker reactions.

Mechanochemical Lignin-Mediated Strecker Reaction.

A mechanochemical Strecker reaction involving a wide range of aldehydes (aromatic, heteroaromatic and aliphatic), amines, and KCN afforded a library of α-aminonitriles upon mechanical activation. This multicomponent process was efficiently activated by lignocellulosic biomass as additives. Particularly, commercially available Kraft lignin was found to be the best activator for the addition of c...

BEYOND THE HEDGES / by Karen Strecker A & M

Several student proposals for changing the current distribution system will be presented by Student Association President Tim Stout to the Faculty Council Subcommittee in a meeting tonight. Stout will then report back to the SA Curriculum Committee at Monday's meeting at 7 p.m. Discussions between the two groups will continue into next semes ter when the f acu l ty subcommittee will present a p...

A highly enantioselective catalytic Strecker reaction of cyclic (Z)-aldimines.

A range of 3H-indoles and 2H-benzo[b][1,4]thiazines smoothly undergo asymmetric Strecker reaction with ethyl cyanoformate in the presence of a Cinchona alkaloid-based thiourea catalyst at 10 °C to give structurally diverse nitrogen-containing heterocycles in good to excellent yields and with excellent ee.
