Zinc-mediated CH-activation of tetrahydrofuran under mild conditions for the regioselective addition to aryl-propiolates.
The CH-activation of THF is realized in a zinc-mediated process using a dibromocyclopropane as a crucial additive. The highly regioselective addition to aryl-substituted propiolates as well as the regio- and stereoselective addition to diynes are described.
متن کاملSelective conversion of alcohols and phenols to tetrahydropyranyl ethers catalyzed with N-chlorosaccharin under mild and solvent-free conditions
An efficient method is described for the mild and rapid tetrahydropyranylation of alcohols and phenols using a catalytic amount of N-chlorosaccharin (1 mol %) and 3, 4-dihydro-2H-pyran under solvent-free condition at room temperature. Benzylic alcohols and phenols containing electron withdrawing or donating groups in various positions of phenyl ring, cinamyl alcohol, primary, ...

متن کاملConversion of aldoximes into nitriles and amides under mild conditions.
A series of Pd(en)X2 salts were used as catalysts for the conversion of aldoximes into nitriles and amides. Highlights of this protocol include the use of inexpensive polar solvents, including water, and moderate reaction temperatures. A high degree of selectivity in the reaction outcome was observed when using aliphatic vs. aromatic/conjugated aldoximes.
متن کاملIron-Catalyzed Cα-H Oxidation of Tertiary, Aliphatic Amines to Amides under Mild Conditions.
De novo syntheses of amides often generate stoichiometric amounts of waste. Thus, recent progress in the field has focused on precious metal catalyzed, oxidative protocols to generate such functionalities. However, simple tertiary alkyl amines cannot be used as starting materials in these protocols. The research described herein enables the oxidative synthesis of amides from simple, noncyclic t...
