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.Sugimura, Takashi; Yoshikawa, Masato; Yoneda, Tohru; Tai, Akira researched the compound: 2,6-Dimethyl-3,5-heptanedione( cas:18362-64-6 ).Name: 2,6-Dimethyl-3,5-heptanedione.They published the article 《Preparation of optically pure (3S,5S)- and (3R,5R)-2,6-dimethyl-3,5-heptanediol》 about this compound( cas:18362-64-6 ) in Bulletin of the Chemical Society of Japan. Keywords: tartaric acid nickel hydrogenation catalyst; optically pure dimethylheptanediol; heptanediol dimethyl optically pure; asym hydrogenation dimethylheptanedione; heptanedione dimethyl asym hydrogenation. We’ll tell you more about this compound (cas:18362-64-6).
Optically pure 2,6-dimethyl-3,5-heptanediol (I) a new chiral auxiliary, has been prepared by the asym. hydrogenation of 2,6-dimethyl-3.5-heptanedione over tartaric acid NaBr-modified Raney nickel catalyst, and the preferential recrystallization of the hydrogenation product. The absolute configuration of (I) was determined to be 3S,5S by chem. correlation with (-)-Et (S)-3-hydroxy-4-methylpentanoate.
In addition to the literature in the link below, there is a lot of literature about this compound(2,6-Dimethyl-3,5-heptanedione)Name: 2,6-Dimethyl-3,5-heptanedione, illustrating the importance and wide applicability of this compound(18362-64-6).
