offers a facile access to structurally diverse optically active vicinaldiamines. Furthermore, the optically active alpha-amino acid Weinreb amide 11 can be efficiently converted to the corresponding amino ketone by a simple treatment with Grignard reagents. In addition, reduction and alkylation of the optically active alpha-amino ketone into both syn and anti alpha-amino alcohols with almost complete
The present invention relates to an adhesive agent composition, containing an aqueous resin dispersion obtained by subjecting a polymerizable compound (C) containing a compound (C1) having a carbon-carbon unsaturated bond to an emulsion polymerization in the presence of a surfactant (A) represented by a general formula (I) shown below and a surfactant (B) free from a radical-polymerizable substituent.
The substituent D represents a polymerizable unsaturated group, the substituent R0 represents an alkyl group having a carbon number of from 1 to 4, the substituent R1 represents hydrocarbon group having an aromatic ring, and AO represents an oxyalkylene group having a carbon number of from 2 to 4.
