摘要:Polycyclic pyrimidine-2,4(1H,3H)-diones with functionalized alkyl residues at the 1-, the 3-, or both position(s); methods for their synthesis, production, and pharmaceutical preparation. The invention concerns the synthesis of the above-described compounds, their chemical and structural characterization, and the analysis of their physiological/pharmacological activities in vitro and in vivo. These goals have been attained by the specification of routes of synthesis, methods for the production of the compounds, and the presentation of compound-specific characteristics. The substances encompassed by the present invention demonstrate pharmacologically significant collangenase/matrix metalloproteinase inhibitory activities. The specific example 1-(3-mercaptoprop-1-yl)-3-methyl-chinazolin-2,4(1H,3H)-dione will be presented in detail.

标 题:Direct synthesis of organotin alkoxides
发明人：JILEK ROBERT E; REED CHRISTOPHER J; NOVAS BRYAN
权利人:INPRIA CORP
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.

标题:Thiadiazole compounds and methods of using said compounds in agriculture
发明人：CEBALO TONY; WALDE ROBERT A
权利人:AIR PROD & CHEM
摘要:Novel thiadiazole compounds are disclosed which contain in the 5 position, C-linked moieties which are either acyclic hydrocarbon radicals or halogenated acyclic hydrocarbon radicals (in which case each halogen is independently selected from F, Cl and Br). These novel compounds also contain an exocyclic nitrogen in the 2 position, and some of them contain the exocyclic substituent: wherein R3 is a lower acyclic hydrocarbon radical and R4 is either H or a lower acyclic hydrocarbon radical. Synthesis of these compounds is disclosed, including synthesis of those which exhibit isomerism and/or tautomerism. Various of these compounds have various agricultural utilities (e.g. as herbicides, insecticides, acaricides and fungicides), each of them having at least one such biological utility. Methods of using these compounds in phytotoxic fungicidal, acaricidal and insecticidal applications are disclosed.
