On the Diels-Alder dimerisation of cross-conjugated trienes.
The first general synthesis of 1-substituted [3]dendralenes has led to the discovery that conjugating groups significantly enhance the rate of Diels-Alder dimerisation relative to both the parent [3]dendralene and to other substituted systems.
متن کاملAsymmetric aza-Diels-Alder reaction of Danishefsky's diene with imines in a chiral reaction medium
The asymmetric aza-Diels-Alder reaction of chiral imines with Danishefsky's diene in chiral ionic liquids provides the corresponding cycloadduct with moderate to high diastereoselectivity. The reaction has proved to perform better at room temperature in ionic liquids without either Lewis acid catalyst or organic solvent. Chiral ionic liquids are recycled while their efficiency is preserved.
متن کاملAcid-free aza Diels-Alder reaction of Danishefsky's diene with imines.
[reaction: see text] A highly efficient aza Diels-Alder reaction of Danishefsky's diene with imines was found to occur in methanol in the absence of any acids at room temperature to give corresponding 2-substituted dihydro-4-pyridone derivatives in high yields. This reaction can be also carried out in a three-component one-pot reaction manner. The reaction was found to proceed through a Mannich...
متن کاملDiels-Alder cycloaddition strategy for kinetic resolution of chiral pyrazolidinones.
A rare example of the application of a catalytic, enantioselective Diels-Alder cycloaddition to affect a kinetic resolution has been developed. Chiral pyrazolidinones are resolved with high selectivity through a process that utilizes a relay of stereochemical information from a permanent chiral center to a fluxional chiral center to enhance the inherent selectivity of the chiral Lewis acid cata...
متن کاملSynthesis and Diels–Alder cycloaddition reaction of norbornadiene and benzonorbornadiene dimers
Dimeric forms of norbornadiene and benzonorbornadiene were synthesized starting with known monobromide derivatives. The Diels-Alder cycloaddition reaction of dimers with TCNE and PTAD was investigated and new norbornenoid polycyclics were obtained. All compounds were characterized properly using NMR spectroscopy.
