Synthesis of oxazolidinones and derivatives

Recent Literature

Synthesis of oxazolidin-2-ones derivatives was carried out starting from urea and ethanolamine reagents using microwave irradiation in a chemical paste medium in which a catalytic amount of nitromethane absorbs the microwaves and generates hot spots.

An efficient, versatile and practical gram-scale preparation of oxazolidinone, imidazolidinone and dioxolanone is achieved.

A mild and efficient gold(I)-catalyzed rearrangement of propargylic tert-butylcarbamates allows the synthesis of various 5-methylene-1,3-oxazolidin-2-ones, which would be less conveniently obtained using other methods.

Various N-Boc-protected alkynylamines are converted into the corresponding alkylidene 2-oxazolidinones or 2-oxazinones under very mild reaction conditions in the presence of a cationic Au(I) complex in high yield regardless of the substitution at nitrogen and alkyne terminus.

A nickel-catalyzed cycloaddition of aziridines with isocyanates proceeded smoothly to give iminooxazolidine derivatives in good yields. A longer reaction time allowed the isomerization of the iminooxazolidine to the corresponding imidazolidinone derivatives.
