The regiochemistry of the reaction of 2-acylcyclohexanones [containing 2-acyl groups, C(O)R, where R = Me, Et, CH2Ph, CF3, Ph and OMe] with trimethyl orthoformate to obtain the corresponding acetal derivative is reported. Compounds with R = alkyl groups showed to be convenient synthons for a one-pot method to obtain 7,7-dimethoxy alkanoate methyl esters under mild conditions. The results of the reaction of 2-acetylcyclopentanone, -heptanone and -octanone with trimethyl orthoformate are also reported.
