| titleOfInvention | Stereospecific method for preparing 5- (1-hydroxy-2-urethaneethylidene) -2,2-dimethyl-1,3-dioxane-4,6-dione derivative which is a precursor of chiral tetrameric acid derivative |
| abstract | (57) [Abstract] [Purpose] 5- (1-hydroxy-2-urethaneethylidene) -2,2-dimethyl-1,3-dioxane-4, It relates to 6-dione derivatives. Composition: N-untan-protected α-amino acid N- Carboxy-anhydride is at least one selected from tertiary amines in which at least one group is aliphatic or cycloaliphatic 5-reacting with Meldrum's acid in an inert organic solvent medium in the presence of two or more equivalents to the N-carboxy-anhydride of the three tertiary amines, (1-Hydroxy-2-urethane ethylidene) -2,2-dimethyl-1,3-dioxane- It relates to a method for preparing a 4,6-dione derivative. |
