摘要:The presently disclosed subject matter provides a method of synthesizing prostaglandins and prostaglandin analogs comprising the ring closing metathesis of compounds of Formula (I). Also provided are novel compounds of Formula (I) and Formula (II). In addition to their use as synthetic intermediates in the presently disclosed methods, compounds of Formula (II) can be used as prostaglandin and/or prostaglandin analog prodrugs.

摘要:A polymer for use in photoresist compositions is synthesized by effecting polymerization reaction to form a polymerization product mixture and subjecting the mixture to molecular weight fractionation by a liquid phase separation technique using a good solvent and a poor solvent. The fractionation step is iterated at least twice, and one iteration of fractionation includes adding a good solvent which is different from the good solvent added in the other iteration of fractionation.

摘要:Compounds of the structure where W is selected from where Q is oxygen or sulfur, R6 and R7 are hydrogen or alkyl, or R6 and R7, together with the nitrogen atoms to which they are attached, define a radical of formula Z is -CH2-, oxygen, sulfur, or -NR9, L1 and L2 are selected from a valence bond, alkylene, propenylene, and propynylene; R1 and R2 are independently selected from alkyl, alkoxy, haloalkyl, halogen, cyano, amino, alkoxycarbonyl, and dialkylaminocarbonyl; Y is selected from oxygen, >NR10, and L3 is selected from alkylene of one to three carbon atoms, propenylene, propynylene, and R3, R4, and R5 are hydrogen or alkyl of one to four carbon atoms inhibit the synthesis of leukotrienes. These compounds are useful in the treatment or amelioration of allergic and inflammatory disease states.
