The invention relates to a process for preparing carbonate and carbamate compounds, which are important intermediates in the synthesis of 6-O-substituted macrolide antibiotics. The process employs metal-catalyzed coupling reactions to provide a carbonate or carbamate of formula (I) or a substrate that can be reduced to obtain the same.
