标题 :Amino or thiol linker building block for the synthesis of amino- or thiol-functionalized nucleic acids and methods of making and use thereof
发明人：WEISS PATRICK A; WEISS VIOLETTE Y; PITSCH STEFAN
权利人:OPERON BIOTECHNOLOGIES INC
摘要:An amino or thiol linker building block for the synthesis of amino or thiol functionalized amino acids and generally of the following structure: n nis provided. Such building block may be introduced in the 5′ end position of an amino acid under standard coupling conditions. Such building block allows in-line coupling control, “trityl-onâ€? purification, and solid support functionalization/derivatization. Such building block is a stable, solid compound and can therefore be easily handled. With the building block of the present invention, deprotection may be carried out under standard detritylation conditions.

标 题 :Biocatalytic synthesis of strained carbocycles
发明人：CHEN KAI; HUANG XIONGYI; KAN S B JENNIFER
权利人:CALIFORNIA INST OF TECHN
摘要:Provided herein are methods for producing products containing strained carbocycles, such as cyclopropene moieties and/or bicyclobutane moieties. The methods include combining an alkyne and a carbene precursor in the presence of a heme protein, e.g., a cytochrome P450, under conditions sufficient to form the strained carbocycle. Reaction mixtures for producing strained carbocycles are also described, as well as whole-cell catalysts comprising heme proteins and variants thereof for forming cyclopropenes, bicyclobutanes, and related products.

权利人:PIRRI JAQUELYN P; HOSTETTLER FRITZ
摘要:Wide range of polyurethane products, e.g., cellular, dense elastomer, and integral skin microcellular products, obtained by the reaction of (a) a polyisocyanate compound, (b) a polyol, (c) optionally a chain extender and/or blowing agent with/without other known additives, (d) in the presence of a nonhydroxyl flow modifier characterized by carbon and hydrogen atoms, at least one and, generally, a plurality of oxyalkylene groups, and at least one urethane, $(1,5)omicronp. Several of the polyurethane products exhibit unique properties, e.g., foamed articles with capability to conduct static electricity, soft elastomers characterized by improved coefficient of friction, etc. Several classes of the flow modifiers are novel per se. The polyurethane products can be synthesized via the one shot or prepolymer process. Multipackage systems, in particular, two and three component systems are useful in molding operations, e.g., manufacture of shoe soles.
