A suite of odd and even carbon-numbered spiroacetals in Bactrocera latifrons. Synthesis and stereochemistry
摘要:
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 = methyl, ethyl, (n)propyl, (n)butyl) which are shown by synthesis and enantioselective gas chromatography to possess the (2S, 6R, 8S) stereochemistry.
