摘要:
A method for producing a compound represented by General Formula (1), the method including: reacting a compound represented by General Formula (3) and a compound represented by General Formula (4): where R1 and R2 each represent aliphatic group which may have substituent, or aromatic group which may have substituent (with the proviso that R1 and R2 are different groups), R3 represents aromatic group which may have substituent, and R4 represents aliphatic group which may have substituent, or aromatic group which may have substituent, where R1 and R2 each represent aliphatic group which may have substituent, or aromatic group which may have substituent (with the proviso that R1 and R2 are different groups), and R3 represents aromatic group which may have substituent, where R4 represents aliphatic group which may have substituent, or aromatic group which may have substituent.
摘要:
The present invention relates to a method of enantioselective addition to imines, including: reacting R3CH═NY with R4ZnR5 in the presence of a compound represented by the following formula (I), in which Y, R1, R2, R3, R4 and R5 are defined the same as the specification. Accordingly, the present invention can prepare secondary amines in high yields and enantiomeric excess by the above-mentioned method.
摘要:
This invention relates to a method to modulate exogenous gene expression in which an ecdysone receptor complex comprising: a DNA binding domain; a ligand binding domain; a transactivation domain; and a ligand is contacted with a DNA construct comprising: the exogenous gene and a response element; wherein the exogenous gene is under the control of the response element and binding of the DNA binding domain to the response element in the presence of the ligand results in activation or suppression of the gene. The ligands comprise a class of ketones.
