Controlling stereoselectivity by enzymatic and chemical means to access enantiomerically pure (1S,3R)-1-benzyl-2,3-dimethyl-1,2,3,4-tetrahydroisoquinoline derivatives
(Elsevier, 2013-06-30)
A chemoenzymatic strategy for the synthesis of enantiomerically pure novel alkaloids (1S,3R)- 1-benzyl-2,3-dimethyl-1,2,3,4-tetrahydroisoquinolines is presented. The key steps are the biocatalytic stereoselective reductive ...
Polymer-Supported Stereoselective Synthesis of Tetrahydro-2H-oxazolo[3,2-a]pyrazin-5(3H)-ones from N-(2-Oxo-ethyl)-Derivatized Dipeptides via Eastbound Iminiums
(American Chemical Society, 2013-02)
Polymer-supported N-(2-oxo-ethyl)-derivatized Ser/Thr/Cys-containing dipeptides were synthesized and subjected to acid-mediated tandem N-acylium ion cyclization−nucleophilic addition to yield tetrahydro-2H-oxazolo- ...

Palladium-catalyzed stereoselective hydrostannation of substituted propargyl alcohols with trineophyltin hydride
(Elsevier Science Sa, 2008-05)
This paper reports results obtained in a study on the palladium-catalyzed hydrostannation of substituted propargyl alcohols with the bulky trineophyltin hydride (1). The reaction of 1 with 10 propargyl alcohols containing ...
Synthesis, Stereoselective Reactions, and Reactivity of 9-Triptycyldimethyltin Hydride
(American Chemical Society, 2005-04)
The synthesis of the new compounds 9-triptycyldimethyltin bromide (2) and 9-triptycyldimethyltin hydride (3) and some of their physical properties are described. The radical addition of 3 to methyl (E)-2,3-diphenylpropenoate ...
Stereoselective hydrostannation of substituted alkynes with trineophyltin hydride
(Elsevier Science Sa, 2002-05)
Hydrostannation of mono- and disubstituted alkynes with trineophyltin hydride (1) leads to vinylstannes in good to excellent yields the configuration of the products depending on the reaction conditions. Thus, whereas ...
