So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Beck, Thorsten M.; Breit, Bernhard researched the compound: 2,6-Dimethyl-3,5-heptanedione( cas:18362-64-6 ).HPLC of Formula: 18362-64-6.They published the article 《Regio- and enantioselective rhodium-catalyzed addition of 1,3-diketones to allenes: Construction of asymmetric tertiary and quaternary all carbon centers》 about this compound( cas:18362-64-6 ) in Angewandte Chemie, International Edition. Keywords: chiral branched allylated diketone synthesis tertiary quaternary carbon center; allene regioselective enantioselective rhodium catalyst phosphoramidite addition diketone allene; crystal structure phenylhexenyl bistrifluoromethyl phenyl propanedione solvent effect; 1,3-diketones; allenes; asymmetric catalysis; rhodium; γ,δ-unsaturated ketones. We’ll tell you more about this compound (cas:18362-64-6).
An unprecedented highly regio- and enantioselective rhodium-catalyzed addition of 1,3-diketones to terminal and 1,1-disubstituted allenes furnishing asym. tertiary and quaternary all-carbon centers is reported. By applying a RhI/phosphoramidite/TFA catalytic system under mild conditions, the desired chiral branched α-allylated 1,3-diketones could be obtained in good to excellent yields, with perfect regioselectivity and in high enantioselectivity. The reaction shows a broad functional-group tolerance on both reaction partners highlighting its synthetic potential.
After consulting a lot of data, we found that this compound(18362-64-6)HPLC of Formula: 18362-64-6 can be used in many types of reactions. And in most cases, this compound has more advantages.
