A series of multi-substituted oxazolidin-2-(thi)one derivatives were prepared via 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) promoted nucleophilic addition/cyclization from alkynyl alcohol and isocynate or thiocynate in high yields of 75%~95%. This concise and efficient approach provides a facial access to a library of biological (Z)-arylmethylene substituted oxazolidin-2-(thi)one derivatives with high stereo-selectivities.

Key words: oxazolidin-2-(thi)one, 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), stereo-selectivity
