The solid phase synthesis of cyclic ureas and thioureas is described. The reduction of acylated dipeptides followed by treatment with carbonyldiimidazole or thiocarbonyldiimidazole affords the corresponding cyclic urea or thiourea in good yield and high purity. This is an example of a broader approa
Barton esters were prepared starting from different carboxylic acids loaded on a Wang resin. Light induced fragmentation occurred giving a radical that reacted with CBrCl 3 to give the corresponding bromides, whereas conjugate addition to electron-poor alkenes proved to be less synthetically useful.
