Exempel på hur man kan använda REGIOSELECTIVE i en mening

• With unsymmetrical alkenes or alkynes, the reaction is rarely regioselective, although some patterns can be observed.
• When used as a ligand, complexed to copper(I), it allows for quantitative, regioselective formal Huisgen 1,3-dipolar cycloadditions between alkynes and azides, in a variety of aqueous and organic solvents.
• This reaction is regioselective because the iminium ion preferentially attacks the nitro ortho position and not the para position.
• These reactions are highly stereo- and regioselective, and have the potential to form four new contiguous stereocenters.
• In organic synthesis, among its many applications, it is particularly useful in directing regioselective O-alkylation, acylation, and sulfonation reactions for diols and polyol.
• Unlike all other clinically used tetrahydroisoquinolinium agents except cisatracurium, gantacurium is a stereo- and regioselective single isomer.
• use of metal complex compounds for chemo- and regioselective catalytic and stoichiometric functionalization of organic compounds that do not exhibit reactivity and / or selectivity hydrophosphoryl compounds in conditions of classical synthesis of organophosphorus compounds.
• He developed original techniques for the production of a number of azomethine and azole compounds, stereo- and regioselective synthesis of their complexes with various metals.
• His notable achievements include the development of processes for the highly regioselective hydroformylations of fluoro-olefins, synthesis of N-acylfluoroamino acids via hydroformylation-amidocarbonylation of fluoro-olefins, synthesis of a-trifluoromethylacrylic acid via carboxylation, novel ureidocarbonylation, synthesis of optically pure fluoroamino acids via enzymatic kinetic resolution, etc.
• Abyu is one of very few enzymes that are able to catalyze pericyclic reactions which effectively form regioselective and stereoselective carbon-carbon bonds.
