A One-Pot Iodo-Cyclization/Transition Metal-Catalyzed Cross-Coupling Sequence: Synthesis of Substituted Oxazolidin-2-ones from N-Boc-allylamines
A one-pot iodo-cyclization/transition metal-catalyzed cross-coupling sequence is reported to access various C5-functionalized oxazolidin-2-ones from unsaturated N-Boc-allylamines. Depending on the Grignard reagents used for the cross-coupling, e.g., aryl- or cyclopropylmagnesium bromide, a cobalt or copper catalyst has to be used to obtain the functionalized oxazolidin-2-ones in good yields.

Cyclizative atmospheric CO2 fixation by unsaturated amines with t-BuOI leading to cyclic carbamates
A cyclizative atmospheric CO2 fixation by unsaturated amines such as allyl and propargyl amines under mild reaction conditions, efficiently leading to cyclic carbamates bearing a iodomethyl group, have been developed utilizing tert-butyl hypoiodite (t-BuOI).
Convenient synthesis of oxazolidinones and oxazinones from allyl and homoallyl amines under mild conditions
An efficient one-pot general method for the high-yield synthesis in solution of oxazolidinones and oxazinones from allyl- and homoallylamines, respectively, has been developed. The reaction is carried out at an atmospheric pressure between 0°C and room te
