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 Synthesis of 1,11,11-trimethyl-3,6-diazatricyclo [6.2.1.02,7]undeca-2,6-diene and 1,15,15-trimethyl-3,10-diazatetracyclo[10.2.1.02,11.04,9]pentadeca-2,4(9),5,7,10-pentaene from camphoroquinone enantiomers, published in 2007-01-31, which mentions a compound: 560-09-8, mainly applied to camphordihydropyrazine preparation; camphorquinoxaline preparation; bromocamphor oxidation diamine cyclocondensation, Formula: C10H16O4.
Optically active camphordihydro-2,3-pyrazine and camphorquinoxaline were prepared from camphoroquinone enantiomers. It was shown that (1S,4R)-(+)-camphoroquinone was formed by oxidation of (1S,3R, 4R)-(-)-3-bromocamphor and (1R,4S)-(-)-camphoroquinone from (1R,3S, 4S)-(+)-3-bromocamphor, resp. Camphor anhydride was a side product (6-10%) of the reaction.
Compound(560-09-8)Formula: C10H16O4 received a lot of attention, and I have introduced some compounds in other articles, similar to this compound((1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid), if you are interested, you can check out my other related articles.
