标 题:Process for the preparation of ketoalkynoic acids and use of the process in an improved synthesis of 2-(substituted)-cyclo-pentane-1,3,4-triones
发明人：REVERMAN LAWRENCE FRANCIS
权利人:MILES LAB
摘要:Reaction of a 2-methyl-2-(alkenyl)-1,3-dioxolane with an α,ω-dihalogenoalkane to obtain a 2-methyl-2-(ω-chloroalkynyl)-dioxolane, conversion of the latter to a corresponding nitrile, and hydrolysis of the nitrile to form a ketoalkynoic acid is a novel process for preparing the acid. n Use of the process in the synthesis of 2-(substituted)-cyclopentane-1,3,4-triones improves that synthesis.

权利人:UNIV KENTUCKY RES FOUND
摘要:The present disclosure relates to the synthesis of non-natural analogs of S-adenosyl-L-methionine (SAM) and/or of Se-adenosyl-L-methionine (SeAM) by reacting a methionine analog and adenosine triphosphate (ATP) in the presence of at least one methionine adenosyltransferase (MAT), and to use thereof with downstream SAM and/or SeAM utilizing enzymes. The non-natural analogs of SAM and/or SeAM have the general formula: n nwhere X is S or Se, and R 1 is an alkyl group.

标 题:Methods for selective N-9 glycosylation of purines
发明人：ROBINS MORRIS J; ZHONG MINGHONG
权利人:UNIV BRIGHAM YOUNG
摘要:A process for providing regiospecific and highly stereoselective synthesis of 9-β anomeric purine nucleoside analogs is described. The introduction of the sugar moiety on to 6-(azolyl)-substituted purine bases is performed so that highly stereoselective formation of the β anomers of only the 9 position regioisomers of the purine nucleoside analogs (either D or L enantiomers) is obtained. This regiospecific and stereoselective introduction of the sugar moiety allows the synthesis of nucleoside analogs, and in particular 2′-deoxy, 3′-deoxy, 2′-deoxy-2′-halo-arabino and 2′,3′-dideoxy-2′-halo-threo purine nucleoside analogs, in high yields without formation of the 7-positional regioisomers. Processes for providing novel 6-(azolyl)purines for the regiospecific and highly stereoselective synthesis of 9-β anomeric purine nucleoside analogs are described. The compounds are drugs or intermediates to drugs.

标 题:Direct synthesis of organotin alkoxides

摘要:Synthesis techniques are described for forming organotin trialkoxide compounds via direct alkylation of tin alkoxides. A first method involves reacting an alkali metal tin trialkoxide with an organohalide compound (RXn, where X is a halide atom and n≥1) to form a monoorgano tin trialkoxide represented by the formula R[Sn(OR′)3]n. The method can be used to form polytin trialkoxide compounds with a plurality of radiation sensitive C—Sn bonds. R and R′ include organo groups and can optionally comprise hetero-atoms and/or unsaturated bonds. A second method involves the ultraviolet light-driven reaction of a di-tin tetraalkoxide with an organohalide compound (RX) to form a monoorgano trialkoxide represented by the formula RSn(OR′)3. A third method involves the visible or ultraviolet light-driven reaction of a di-tin tetraalkoxide or an alkali metal tin trialkoxide with an fluorinated organohalide compound (RFX) to form a fluorinated monoorgano trialkoxide represented by the formula RFSn(OR′)3. The disclosed methods provide for high mono-organo specificity. Corresponding organotin trialkoxide compositions are also described. The compositions are useful for radiation patterning, especially with EUV radiation. The organotin trialkoxide compositions may be formed as radiation-patternable coatings on substrates.
