The base-promoted switchable synthesis of five- and six-membered cyclic carbamates using atmospheric pressure carbon dioxide as the C1 source was developed. The chemoselectivity of products was simply controlled by changing bases and solvents. The reaction proceeds effectively under mild conditions, affording valuable cyclic carbamates. Experimental results and DFT studies revealed the reaction mechanism.

A process for preparing bisoprolol comprises reacting oxazolidinone sulphonate with 4-hydroxybenzylaldehyde to form oxazolidinone benzaldehyde, forming oxazolidone benzylalcohol from oxazolidone benzaldehyde, and subsequently reacting oxazolidinone benzylalcohol with isopropyl oxitol to form bisoprolol base. Oxazolidone sulphonate and oxazolidone benzaldehyde are novel intermediates.
