A hydantoin derivative represented by formula (I):
wherein the all symbols are defined in the disclosure. The hydantoin derivative has an inhibitory activity on metalloprotease and hence is useful as analgesic and cardiovascular drug.
The new chiral aminodiphosphinite ligands are readily prepared from chiral amino acids. These compounds were characterized by 13C and 31P NMR spectroscopy and their behaviour as homogeneous catalysts was investigated in the linear dimerization of butadiene.
新的手性氨基二亚膦酸酯配体易于从手性氨基酸制备。这些化合物通过13 C和31 P NMR光谱进行表征,并在丁二烯的线性二聚反应中研究了它们作为均相催化剂的行为。
