BF3·Et2O-mediated synthesis of multisubstituted indenes from alkyl aryl-1,3-dienes and aromatic aldehydes through tandem addition/4π-electrocyclization/benzylation via tetrahydroindeno-oxepine/quinone methide followed by an intramole
2-(3,5-Dinitrophenyl)-1,3-dithiane carbanion: A benzylic anion with a low energy triplet state
Perrotta, Raffaele R.,Winter, Arthur H.,Coldren, William H.,Falvey, Daniel E.
experimental part, p. 15553 - 15558 (2011/11/13)
Calculations at the DFT level predict that benzyl anions with strong π-electron-withdrawing groups in the meta position(s) have low energy diradical or triplet electronic states. Specifically, the 2-(3,5-dinitrophenyl)- 1,3-dithiane carbanion is predicted
Enzyme-Catalyzed Organic Synthesis: NAD(P)H Cofactor Regeneration by Using Glucose 6-Phosphate and the Glucose-6-Phosphate Dehydrogenase from Leuconostoc mesenteroides
Wong, Chi-Huey,Whitesides, George M.

Glucose 6-phosphate dehydrogenase (from Leuconostoc mesenteroides) and glucose 6-phosphate comprise a useful system for regeneration of reduced nicotinamide cofactors for use in enzyme-catalyzed organic sysnthesis.This enzyme is approximately equally active in reduction of NAD and NADP.It is commercially available, inexpensive, stable, and easily immobilized.Glucose 6-phosphate can be prepared in quantity by hexokinase-catalysed phosphorylation of glucose by ATP (coupled with ATP regeneration) or by other methods.The operation in this regeneration system is illustrated by syntheses of enantiomerically enriched D-lactic acid (0.4 mol, enantiomeric excess 95percent) and (S)-benzyl-α-d1 alcohol (0.4 mol, enantiomeric excess 95percent) and by synthesis of treo-DS(+)-isocitric acid (0.17 mol).Factors influencing the stability of NAD(P)(H) in solution have been explored.
