, p. 3717 - 3727 (2021/07/10)
An alternative method for the synthesis of new GFP chromophore analogous that possess good photo physical properties which can be used as efficient biomarkers. These compounds have low fluorescence most probably due to their Z–E photo isomerization. These

The efficient synthesis of 4-arylidene-2-phenyl-1H-imidazol-5(4H)-ones was achieved via microwaveassisted reactions of 4-arylmethylene-2-phenyloxazol-5(4H) -ones with urea in glycol. This approach provides a facile shortcut for the synthesis of this type

, p. 657 - 660 (2007/10/02)
Twenty five unsaturated 2,4-disubstituted 2-imidazolin-5-ones (IV) have been prepared in 23-71percent yields by condensing aromatic aldehydes with a mixture of ethyl chloroacetate and an aromatic amidinium chloride in the presence of sodium hydrogencarbonate.Twenty three of them have also been prepared in 62-97percent yields by this method using ethyl bromoacetate instaed of the chloroacetate.Further, two unsaturated 2-imidazolin-5-ones (IV) have been prepared by these two methods using cyclohexanone (yields 33percent each) and cinnamaldehyde (yields 0 and 18percent) instead of the aromatic aldehydes.
Synthesis of Acylamino Acid Amides and Acylamino Acids via 2,4-Disubstituted 2-Imidazolin-5-ones

, p. 70 - 72 (2007/10/02)
Unsaturated 2,4-disubstituted 2-imidazolin-5-ones (I) have been reduced with a mixture of hydriodic acid and red phosphorus in the presence of acetic anhydride to give the saturated 2,4-disubstituted 2-imidazolin-5-ones (II) which have been hydrolysed to acylamino acid amides (III) and acylamino acids (IV) with sodium hydroxide solution under different conditions.In all six acylamino acid amides (23 - 51percent yields) and four acylamino acids (26 - 65percent yields) have been prepared.One saturated 2-imidazolin-5-one, namely 2-phenyl-4-benzyl-2-imidazolin-5-one has been isolated from the reaction in 40percent yield and identified.
