Cis And Trans

Alkylation of 2-tert-butyl-5-X-1,3-dioxanes (X = CO2CH3, COPh, and NO2) was studied. Products resulting from an equatorial approach of the alkylating agent are preferentially formed when X = CO2CH3 and NO2. Also, the cis isomers that have an equatorial hydrogen at C-5 were found to deprotonate at a faster rate than the trans isomers when X = CO2CH3, COPh, CHO, and CN. These results are compared with those obtained with methyl 2-tert-butyl cyclohexane carboxylate and are interpreted by taking into account stereoelectronic principles.
