- W1995102412 abstract "Conjugate addition of trinethyltinlithium to cyclohex-2-enone followed by enolate trapping with alkylating agents provide traus-2-alkyl-3-trimethylstannylcyclohexanones, which on reaction with Grignard reagents derived from 4-bromo-1-butene or 5-bromo-1-pentene afford tertiary γ-stannylcyclohexanols in a highly diastereoselective fashion. Triaethylstannyl-triggered ring fragmentation (by lead tetraacetate in benzene) leads efficiently to dienones, which on hydroxymercuration, cyclisation and reduction provide a range of 1,6-dioxaspiro[4.5]decanes and 1,7-dioxaspiro[5,5]undecanes, some of which are of insect origin. Epoxidation of these dienones, followed by acid catalysed hydrolysis and cyclisation leads to hydroxy substituted spiroacetals. Syntheses of 6-oxononan-1-ol (a glandular component of the fruit flies, D. halfordiae and D. occipitalis) andE-6-nonene-2-one, which is transformed readily intoexo or endo-brevicomin, are also presented. Some dialkyl substituted [4.5]- and [5.5] spiroacetals have been acquired also by free radical addition reactions etc., utilising organomercury chemistry." @default.
