A novel, tandem construction of C-N and C-C bonds: facile and one-pot transformation of the Baylis-Hillman adducts into 2-benzazepines.
A novel reaction involving tandem construction of C-N and C-C bonds via the simultaneous Ritter and Houben-Hoesch reactions on Baylis-Hillman adducts leading to a convenient, one-pot synthesis of 2-benzazepine derivatives is described. A facile stereoselective transformation of the Baylis-Hillman adducts into (E)- and (Z)-allyl amides is also presented.
متن کاملSynthesis of allyl selenides by palladium-catalyzed decarboxylative coupling.
This communication details the Pd-catalyzed decarboxylation of selenocarbonates; use of a chiral nonracemic catalyst affords enantioenriched allyl selenides which undergo stereospecific [2,3]-sigmatropic rearrangements to form enantioenriched allylic amines and chlorides.
متن کاملSynthesis of hydrazinoheterocycles from Morita-Baylis-Hillman adducts of nitroalkenes with azodicarboxylates.
Conjugated nitroalkenes and nitrodienes undergo smooth α-hydrazination with azodicarboxylates through an imidazole catalyzed carbon-heteroatom bond formation under Morita-Baylis-Hillman conditions. The resulting hydrazinonitroalkenes take part in 1,3-dipolar cycloaddition with azide under mild conditions to give hydrazinotriazoles. A [3 + 2] annulation with phenols and naphthols involving Micha...
متن کاملA Single-Flask Synthesis of Morita-Baylis-Hillman Adducts from Ethoxyacetylene and Carbonyl Compounds: Synthesis of Subamolides D and E.
Sequential treatment of (ethoxyethynyl)lithium with aldehydes and/or ketones (2 and 4) and BF3·OEt2 gives rise to β-hydroxyenoates 5 in good to excellent overall yields. Similarly, the combination of 1 (M = Li) and dicarbonyl compounds 6 (X = O) or keto/aldehyde acetals (X = OMe) followed by the addition of a Lewis acid leads to five-, six-, and seven-membered hydroxycycloalkene carboxyates. Th...
متن کاملMicrowave-Assisted Convenient Syntheses of 2-Indolizine Derivatives from Morita-Baylis-Hillman Adducts: New in silico Potential Ion Channel Modulators
Neste artigo, um estudo sintético assistido por irradiação de micro-ondas para produzir 2-indolizina-carbonitrila e 2-indolizina-carboxilato de metila em bons a altos rendimentos (70 e 81%) em uma etapa a partir de adutos de Morita-Baylis-Hillman (AMBH) é apresentado. Estes compostos foram subsequentemente transformados em altos rendimentos (94-100%) em três derivados 2-indolizínicos. Os cinco ...
