چکیده
ortho-Lithiation of cyclic aryl sulfonamides in the presence of phosphoryl chloride provides a very simple entry to fused polycyclic sultams (benzothiazolines and naphthathiazolines).

One-pot Multi-step Synthesis of some Aromatic Salicylaldoximes Using MgO Nanoparticles
MgO nanopartticels (NP-MgO) in average size between 30—130 nm were prepared by sonochemistry method. Some phenols have been converted to ortho-hydroxybezaldehyd by ortho-formylation using MgO nanoparticles and (CH2O)n in xylene and subsequently treated with aqueous NH2OH.HCl, affording the corresponding aldoxime in a one-pot procedure. Moreover, this one-pot process, with two transformations, o...
متن کاملOne-pot Crabbé homologation-radical cascade cyclisation with memory of chirality.
The tandem Crabbé homologation-radical rearrangement of terminal enediynes leads, in a one-pot procedure, to the enantioselective synthesis of six- and seven-membered ring α-aminoesters bearing a quaternary stereocenter based on the phenomenon of memory of chirality.
متن کاملGold-catalyzed one-pot cascade construction of highly functionalized pyrrolo[1,2-a]quinolin-1(2H)-ones.
An efficient protocol was developed for the synthesis of fused heterocyclic multiring compounds pyrrolo[1,2-a]quinolin-1(2H)-ones via a AuBr(3)/AgSbF(6)-catalyzed cascade transformation. Significantly, the strategy affords a straightforward and efficient approach to construction of tricyclic lactam molecular architectures in which two new C-C bonds and one new C-N bond are formed in a one-pot s...
متن کاملOne-pot synthesis of tri- and tetrasubstituted imidazoles using nano-LaMnO3 perovskite-type oxide as reusable heterogeneous catalyst in solvent-free condition
A convenient synthetic method for the synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetra substituted imidazole derivatives, has been developed via one-pot condensation reaction in solvent-free condition when aldehyde, ammonium acetate/amine, and 1,2-diketone are reacted using 0.8 mol% of NP-LaMnO3 at 80 °C under solvent free conditions. Catalyst could be recovered and reused in five reaction c...
