A novel reductive cyclization of arylmethylidenemalononitrile promoted by samarium diiodide
Carbon]carbon bond formation is the essence of organic synthesis and the reductive dimerization of carbonyl derivatives is a most valuable method for establishing carbon]carbon bonds. Since the time Kagan demonstrated a simple preparation of samarium diiodide from samarium metal and 1,2-diiodoethane, SmI2 has been developed as a mild, neutral and versatile single electron transfer reductant. It...
متن کاملIndole synthesis from N-allenyl-2-iodoanilines under mild conditions mediated by samarium(II) diiodide.
A novel method for indole skeleton synthesis under mild conditions mediated by samarium(ii) diiodide has been developed. The reaction of N-allenyl-2-iodoaniline derivatives with SmI2 in the presence of HMPA and i-PrOH at 0 °C afforded indole derivatives in high yields.
متن کاملA new approach to 3-hydroxyprolinol derivatives by samarium diiodide-mediated reductive coupling of chiral nitrone with carbonyl compounds.
A flexible diastereoselective approach to trans-(3S)-hydroxyprolinol derivatives is described, which is based on the samarium diiodide-mediated reductive coupling of the chiral 1-pyrroline N-oxide (nitrone)(S)-10 with carbonyl compounds. The reductive hydroxyalkylation of nitrone 10 with ketones and aromatic aldehydes is highly diastereoselective in establishing the C-2 chiral center of the pyr...
متن کاملNew samarium diiodide-induced cyclizations*
Samarium diiodide (SmI2) smoothly promotes the cyclizations of suitably substituted carbonyl compounds with styrene subunits leading to benzannulated cyclooctenes. The intramolecular samarium ketyl addition to arene or hetarene moieties enables a new, efficient, and highly stereoselective entry to dearomatized products such as hexahydronaphthalenes, steroid-like tetraor pentacyclic compounds, o...
متن کاملHighly enantioselective [4+2] annulation via organocatalytic Mannich-reductive cyclization: one-pot synthesis of functionalized piperidines.
A new method for one-pot synthesis of 2,3-substituted piperidine from N-PMP aldimine and aqueous glutaraldehyde via formal [4+2] cycloaddition is reported. This reaction involves organocatalytic direct Mannich reaction-reductive cyclization with high yields (up to 90%) and excellent enantioselectivities (up to >99%). The practicability of this method is also shown at a gram scale as well as thr...
