Selective hydrogenation of amino acid methyl esters to chiral amino alcohols is an important and fascinating process. The CuZn0.3Mg0.1AlOx catalyst for the synthesis of chiral amino alcohols was prepared by the fractional
Biodegradable bio-absorbable material for clinical practice and method for producing the same

Page/Page column 2, (2010/02/13)
Bio-absorbable polymers such as vascular stent and suture thread for use as materials for clinical practice have almost definite dynamic properties such as tensile strength and degradation rate for absorption. When the dynamic properties thereof are elevated, therefore, the bio-absorbable polymers turn fragile, involving slower degradation rate. When the degradation rate is elevated, further, the dynamic properties are deteriorated. Disadvantageously, such bio-absorbable polymers have limited purposes for use and limited sites for use. Thus, copolymerization of bio-absorbable polymers with a cyclic depsipeptide to form a copolymer of the ring-opened and copolymerized depsipeptide can allow the adjustment of the dynamic properties and degradation rate of the resulting copolymer depending on the content of the depsipeptide.

A process for the preparation of 3- and/or 6-substituted 2,5-morpholinediones is disclosed. Such morpholinediones are useful as precursors for the preparation of depsipeptide polymers and copolymers.
