摘要:
Compounds of Formula I with activity against HIV, including pharmaceutical compositions and methods for using these compounds in treating human immunodeficiency virus (HIV) infection, are set forth:
摘要:
In general, the invention features compounds useful for the synthesis of analogs of halichondrin B, such as eribulin or pharmaceutically acceptable salts thereof, e.g., eribulin mesylate. Exemplary compounds are of formula (I), (II), or (III):
摘要:
Provided herein are small molecule active metabotropic glutamate subtype-2 and -3 receptor negative allosteric modulators (NAMs), compositions comprising the compounds, and methods of using the compounds and compositions.
摘要:
Provided herein are methods of producing dialkylfurans, such as 2,5-dimethylfuran, and other alkyl furans, such as 2-methylfuran. For example, 2,5-dimethylfuran may be produced by hydrogenation of (5-methylfuran-2-yl) methanol or 2-(chloromethyl)-5-methylfuran in the presence of a solid supported metal catalyst having an excess of either basic or acidic sites (as determined by chemisorption of CO2 or NH3). The process could further include a urea reagent (TMU, DMPU, TMI) and an alkyl benzene.
摘要:
Disclosed are compounds having the formula: wherein R1, R2 and R3 are as defined herein, and methods of making and using the same, including use as inhibitors of BMP1, TLL1 and/or TLL2 and in treatment of diseases associated with BMP1, TLL1 and/or TLL2 activity.
摘要:
The present invention relates to compounds of the formula I in which the parameters have the respective meanings given in the description, to the use thereof for high-frequency components, to liquid-crystalline media comprising the compounds, and to high-frequency components, in particular antennae, especially for the gigahertz range, comprising these media. The liquid-crystalline media serve, for example, for the phase shifting of microwaves for tunable ‘phased-array’ antennae.

摘要:
A method for increasing the rate of phosphine oxide reduction, preferably during a Wittig reaction comprising use of an acid additive is provided. A room temperature catalytic Wittig reaction (CWR) the rate of reduction of the phosphine oxide is increased due to the addition of the acid additive is described. Furthermore, the extension of the CWR to semi-stabilized and non-stabilized ylides has been accomplished by utilization of a masked base and/or ylide-tuning.
