The invention relates to inhibitors of PI5P4K inhibitors useful in the treatment of cancers, neurodegenerative diseases, inflammatory disorders, and metabolic diseases, having the Formula (I); where A1, A2, G, R1, R2, R3, R4, and W are described herein.
DC-SIGN and Langerin are two C-type lectins involved in the initial steps of HIV infections: the former acts as a viral attachment factor and facilitates viral invasion of the immune system, the latter has a protective effect. Potential antiviral compounds targeted against DC-SIGN were synthesized using a common fucosylamide anchor. Their DC-SIGN affinity was tested by SPR and found to be similar to that of the natural ligand Lewis-X (LeX). The compounds were also found to be selective for DC-SIGN and to interact only weakly with Langerin. These molecules are potentially useful therapeutic tools against sexually transmitted HIV infection.

Disclosed herein is a method that includes contacting (a) a gaseous mixture that includes (i) an inert gas and (ii) a vaporized liquid feed containing methyl-2-acetoxy propionate (MAPA) and an excipient, with (b) a material having a surface acidity of about 5 micromoles per gram (μmol/g) or less and a surface basicity of about 15 μmol/g or less, under conditions sufficient to produce a conversion product that includes methyl acrylate in a molar yield of at least about 85% from MAPA. The excipient is selected from the group consisting of acetic acid, formic acid, methyl acetate, lactic acid, carbon dioxide, and mixtures thereof. This method now makes possible the ability to further process the manufactured methyl acrylate into acrylic acid by either of two general routes that ultimately produce acrylic acid in a molar yield of at least about 80% from methyl acrylate and, preferably, substantially free of propanoic acid.

formal [2+1] addition of carbene or radical based C1 units to alkenes. In contrast, the one‐pot intermolecular cyclopropanation of alkanes by redoxactive C1 units has remained unrealised. Herein, we achieved this process simply by exposing β‐aryl propionitriles and C1 radical precursors (N‐oxy esters) to base and blue light. The overall process is redox‐neutral and a photocatalyst, whether metal‐ or organic‐based

2-Acetoxyalkanoic acid esters are made in a reaction of a 3,6-dialkyl-1,4-dioxane-2,5-dione or a poly(α-hydroxyalkanoic acid), an acetate ester and an alcohol or phenol in the presence of a transesterification catalyst. Unlike previous methods for making 2-acetoxyalkanoic acid esters, this process proceeds in high yield and high selectivity to the desired product.
