专利号:EP-0310950-B1 优先权日:1983-11-18 标题 :Quinoline intermediates for the synthesis of 1H-imidazo[4,5-c]quinolines and 1H-imidazo[4,5-c]quinolin-4-amimes 摘要:Compounds of the types (I) and (II) are disclosed, wherein each R5 is independently selected from the group consisting of alkyl of one to about four carbon atoms, alkoxy of one to about four carbon atoms and halogen, and n is an integer from 0 to 2, with the proviso that if n is 2, then said R5 substituents together contain no more than 6 carbon atoms; R6 is selected from the group consisting of hydroxyalkyl of one to about six carbon atoms and cyclohexylmethyl; and R7 is selected from the group consisting of alkyl of one to about four carbon atoms and hydrogen. These compounds may be used as intermediates for the synthesis of 1H-imidazo[4,5-c]quinoline derivatives.
专利号:US-6489471-B1 优先权日:1998-06-17 标 题 :Process for the synthesis of carbapenem intermediates, and compounds produced 发明人:HUMPHREY GUY R; MILLER ROSS A; YASUDA NOBUYOSHI 权利人:MERCK & CO INC 摘要:A process of synthesizing a carbapenem compound of formula (6) is disclosed, wherein R represents H or methyl, P and P* independently represent H or protecting groups and each R1 is independently selected from: H, halo, OH, OP wherein P is a protecting group, C1-6 alkyl or C1-6 alkyl substituted with 1-3 of halo, OH, OP, NH2, NHC1-4 alkyl or N(C1-4 alkyl)2, comprising reacting a carbapenem of formula (4') with a compound of formula (7), wherein R, R1, P and P* are as previously defined and R2 represents acetate, C(O)OR' or P(O)(OR'')2, wherein R' and R'' independently represent Clot alkyl, benzyl or aryl, in the presence of a catalyst to produce a compound of formula (6).
专利号:US-5073639-A 优先权日:1988-11-25 标 题:Process for the synthesis of novel and known nitroimidazoles which are useful as sensitizing agents 发明人:SUTO MARK J 权利人:WARNER LAMBERT CO 摘要:The present invention is a novel process for preparing both known and novel nitroimidazoles having novel intermediates. The process advantageously reduces the number of process steps, provides increased yield with both greater safety and greater control of stereoisomerism in the products.
