The synthesis of 2-furoic acid derivatives containing both 3-methoxy and 3-TMS groups is described. Reductive alkylation proceeded well to give us access to a series of highly functionalised dihydrofurans with potential for further elaboration. Of the two groups tested at C-3, the TMS derivative was found to be the more useful and gave rise to high levels of stereoselectivity when attached to a furan
