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.Zhang, Hesheng; Fletcher, Mary T.; Avery, James W.; Kitching, William researched the compound: (S)-2-Bromosuccinic acid( cas:20859-23-8 ).Category: copper-catalyst.They published the article 《A suite of odd and even carbon-numbered spiroacetals in Bactrocera latifrons. Synthesis and stereochemistry》 about this compound( cas:20859-23-8 ) in Tetrahedron Letters. Keywords: spiroacetal synthesis stereochem. We’ll tell you more about this compound (cas:20859-23-8).
Female abdominal tips from the pestiferous fruit-fly species, Bactrocera latifrons (Hendel) provide a suite of odd and even 2-alkyl-8-methyl-1,7-dioxaspiro[5.5]undecanes (alkyl = Me, Et, Pr, nbutyl) which are shown by synthesis and enantioselective gas chromatog. to possess the (2S, 6R, 8S) stereochem.
