In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Palladium-Catalyzed anti-Michael Reductive Heck Reaction of α,β-Unsaturated Esters, published in 2020-07-02, which mentions a compound: 97739-46-3, mainly applied to palladium catalyzed anti Michael reductive Heck unsaturated ester, Recommanded Product: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane.
A general intermol. anti-Michael reductive Heck reaction of α,β-unsaturated esters with organobromides has been developed. Most topical classes of aryl, heteroaryl, and vinyl bromides were found to efficiently react with a variety of internal conjugated alkenes. This protocol set up a platform toward diverse α-arylated 1,6-dicarbonyl frameworks found in natural products and drugs, which are still highly challenging targets in traditional α-arylation protocols because of competitive selectivity of enolation. A removable directing group, gram-scale reaction, and modification of complex mols. have addnl. demonstrated that the anti-Michael reductive Heck reaction is a powerful complementary strategy to the classical α-arylation approaches. Preliminary mechanistic studies are consistent with our proposed mechanistic design.
Although many compounds look similar to this compound(97739-46-3)Recommanded Product: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane, numerous studies have shown that this compound(SMILES:CC1(C2)OC(C3)(C)OC2(C)OC3(C)P1C4=CC=CC=C4), has unique advantages.
