Lactam and oxazolidinone derived potent 5-hydroxytryptamine 6 receptor antagonists

Lactam and oxazolidinone derived potent 5-hydroxytryptamine 6 (5-HT 6) receptor antagonists have been disclosed. One potent member from the lactam series, racemic compound 14 (Ki of 2.6 nM in binding assay, IC50 of 15 nM in functional cAMP antagonism assay) was separated into corresponding enantiomers that displayed the effect of chirality on binding potency (Ki of 1.6 nM and 3000 nM, respectively). The potent enantiomer displayed an IC50 of 8 nM in cAMP antagonism assay, selectivity against a number of family members as well as brain permeability in rats after 6 h post oral administration.

Competitive Hydrogen Atom Transfer to Oxyl- and Peroxyl Radicals in the Cu-Catalyzed Oxidative Coupling of N-Aryl Tetrahydroisoquinolines Using tert-Butyl Hydroperoxide

The question of whether hydrogen atom transfer (HAT) or electron transfer (ET) is the key step in the activation of N-aryl tetrahydroisoquinolines in oxidative coupling reactions using CuBr as catalyst and tert-butyl hydroperoxide (tBuOOH) has been investigated. Strong indications for a HAT mechanism were derived by using different para-substituted N-aryl tetrahydroisoquinolines, showing that electronic effects play a minor role in the reaction. Hammett plots of the Cu-catalyzed reaction, a direct time-resolved kinetic study with in situ generated cumyloxyl radicals, as well as density functional calculations gave essentially the same results. We conclude from these results and from kinetic isotope effect experiments that HAT is mostly mediated by tert-butoxyl radicals and only to a lesser extent by tert-butylperoxyl radicals, in contrast to common assumptions. However, reaction conditions affect the competition between these two pathways, which can significantly change the magnitude of kinetic isotope effects.

Simultaneous engineering of an enzyme’s entrance tunnel and active site: The case of monoamine oxidase MAO-N

A new directed evolution approach is presented to enhance the activity of an enzyme and to manipulate stereoselectivity by focusing iterative saturation mutagenesis (ISM) simultaneously on residues lining the entrance tunnel and the binding pocket. This combined mutagenesis strategy was applied successfully to the monoamine oxidase from Aspergillus Niger (MAO-N) in the reaction of sterically demanding substrates which are of interest in the synthesis of chiral pharmaceuticals based on the benzo-piperidine scaffold. Reversal of enantioselectivity of Turner-type deracemization was achieved in the synthesis of (S)-1,2,3,4-tetrahydro-1-methyl-isoquinoline, (S)-1,2,3,4-tetrahydro-1-ethylisoquinoline and (S)-1,2,3,4-tetrahydro-1-isopropylisoquinoline. Extensive molecular dynamics simulations indicate that the altered catalytic profile is due to increased hydrophobicity of the entrance tunnel acting in concert with the altered shape of the binding pocket.

Safe and Efficient Phosgenation Reactions in a Continuous Flow Reactor

Phosgene is widely used in organic synthesis owing to its high reactivity, utility, and cost efficiency. However, the use of phosgene in batch processes on the industrial scale is challenging owing to its toxicity. An effective method to minimize reaction volumes and mitigate the safety risks associated with hazardous chemicals is the use of flow reactors. Consequently, we have established a flow reaction system using triphosgene and tributylamine, which affords a homogeneous reaction that avoids clogging issues. In addition, we have demonstrated that this methodology can be applied to a wide variety of phosgene reactions, including the preparation of pharmaceutical intermediates, in good to excellent yields.
