Diels-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.
متن کاملMono and double polar [4 + 2(+)] Diels-Alder cycloaddition of acylium ions with O-heterodienes.
Gas-phase reactions of acylium ions with alpha,beta-unsaturated carbonyl compounds were investigated using pentaquadrupole multiple-stage mass spectrometry. With acrolein and metacrolein, CH(3)-C(+)(double bond)O, CH(2)(double bond)CH-C(+)(double bond)O, C(6)H(5)-C(+)(double bond)O, and (CH(3))(2)N-C(+)(double bond)O react to variable extents by mono and double polar [4 + 2(+)] Diels-Alder cycl...
متن کاملMicrowave-assisted sidewall functionalization of single-wall carbon nanotubes by Diels-Alder cycloaddition.
The first Diels-Alder cycloaddition of o-quinodimethane to SWNT has been performed under microwave irradiation.
متن کاملA Study of the Temperature Dependent Healing Capabilities of New Polymers Based on Diels-alder Cycloaddition
Because of its thermal reversibility, the retro-Diels-Alder (RDA) reaction represents an appealing possibility to produce self-healing polymers with well-defined architectures and tunable properties [1]. However, the polymer architecture for which the Diels-Alder (DA) reaction can best be used to contribute to the healing process is still not well-defined. Therefore, new terpolymers containing ...
