A one-pot direct reductive allylation protocol has been developed for the synthesis of secondary amines by using titanium hydride and an allylzinc reagent. This protocol is applicable to a broad range of substrates, including acyclic amides, benzamides, α,β-unsaturated amides, and lactams. The stereochemical outcome obtained from the reaction with crotylzinc reagent suggested that the allylation reaction proceeds through a six-membered cyclic transition state. A total synthesis of (-)-castoramine was accomplished by following this protocol for the highly stereoselective construction of contiguous stereocenters.
Ring-chain tautomerism in 2,2-bis(2-thienyl)-tetrahydrofurans: Preparation of [butene-2H5]-tiagabine
Herberta, John M.,Mathersa, Trevor W.
experimental part, p. 598 - 600 (2011/05/12)
A concise preparation of [butene-2H5]-tiagabine hydrochloride starting from [2H6]-γ-butyrolactone is described. It was necessary to ring-open the labeled γ-butyrolactone precursor before the addition of 2-thienyllithium to avoid cyclisation of the intermediate to a 2,2-bis(2-thienyl)tetrahydrofuran. Copyright
4-Piperidines and 3-pyrrolidines as dual serotonin and noradrenaline reuptake inhibitors: Design, synthesis and structure-activity relationships
Fish, Paul V.,Andrews, Mark D.,Jonathan Fray,Stobie, Alan,Wakenhut, Florian,Whitlock, Gavin A.
scheme or table, p. 2829 - 2834 (2010/03/03)
Single enantiomer [(aryloxy)(pyridinyl)methyl]piperidine and pyrrolidine derivatives 5-9 are inhibitors of monoamine reuptake. Structure-activity relationships established that monoamine reuptake inhibition are functions of amine, pyridine isomer, aryloxy ring substitution and stereochemistry. Consequently, selective NRIs, selective SRIs, dual SNRIs and triple SNDRIs were all identified. Dual SNRIs 5l-a and 9c were evaluated in additional pharmacology and pharmacokinetic studies as representative examples from this series.

The title compounds were prepared from valine-derived N-acylated oxazolidin-2-ones, 1-3, 7, 9, by highly diastereoselective (≥ 90%) Mannich reaction (→ 4-6; Scheme 1) or aldol addition (→ 8 and 10; Scheme 2) of the corresponding Ti- or B-enolates as the key step. The superiority of the '5,5-diphenyl-4-isopropyl-1,3-oxazolidin-2-one' (DIOZ) was demonstrated, once more, in these reactions and in subsequent transformations leading to various t-Bu-, Boc-, Fmoc-, and Cbz-protected β2-homoamino acid derivatives 11-23 (Schemes 3-6). The use of ω-bromo-acyl-oxazolidinones 1-3 as starting materials turned out to open access to a variety of enantiomerically pure trifunctional and cyclic carboxylic-acid derivatives.
