The development of catalyst-controlled, site-selective C(sp 3)-H functionalization reactions is currently a major challenge in organic synthesis. In this paper, a novel bond-weakening catalyst that recognizes the hydroxy group of alcohols through formation of a borate is described. An electron-deficient borinic acid-ethanolamine complex enhances the chemical yield of the α-C-H alkylation of alcohols when used in conjunction with a photoredox catalyst and a hydrogen atom transfer catalyst under irradiation with visible light. This ternary hybrid catalyst system can, for example, be applied to functional-group-enriched-peptides.

Paragraph 0151; 0152, (2017/07/25)
PROBLEM TO BE SOLVED: To provide a novel compound which is suitable for use as a surface treatment agent and has high stability, a surface treatment agent containing the compound, and a surface treatment method. SOLUTION: The compound is represented by formula (I) (R1 to R4 are each independently H, an alkyl group, or an alkoxy group which may have a perfluoroalkyl group as a substituent; R5 is H or a C1-6 alkyl group which may have a halogen atom as a substituent; X is a group represented by -OCONH-, -OCOS-, -OCOO-, -NH-, -S-, -O-, or -OCO-; when X is other than -OCO-, R6 is an alkylene group; and when X is -OCO-, R6 is a single bond or an alkylene group).

Synthesis of methacrylate-functionalized phosphonates and phosphates with long alkyl-chain spacers and their self-aggregation in aqueous solutions
Francova, Denisa,Kickelbick, Guido
experimental part, p. 413 - 422 (2010/06/14)
Polymerizable amphiphilic organophosphorous compounds were synthesized and their self-aggregation behavior was investigated. The studied molecules contain a hydrophilic phosphorus end group, an alkyl chain spacer with a variable length from 3 to 11 CH2 groups and a polymerizable methacrylic group at the other chain end. Thus, the molecules represent a class of polymerizable surfactants. Two different reaction methods were used; either unsaturated alcohols or bromine-containing alcohols were applied as starting compounds for the preparation of the organophosphorous surfactants. The self-aggregation and micelle formation of the prepared compounds were investigated in aqueous solution by dynamic light scattering measurements. The critical micelle concentration of the P-containing amphiphiles was in all cases smaller than 0.040 mol/l and strongly dependent on the polarity of the phorphorous head group and the chain length of the spacer. Graphical abstract: [Figure not available: see fulltext.] The synthesis of organophosphorous amphiphiles as surface active monomers for the modification of metal oxide surfaces is presented. The spacer between the phosphorous head group and the methacrylate group was varied with regard to their length and composition. The self-aggregation behavior of these methacrylate-functionalized phosphates and phosphonates surfactants was investigated.

This invention relates to a class of novel phosphonate derivatives of lipophilic amines which exhibit squalene synthase inhibition properties. More specifically the compounds are bis aryl cycloalkylamino and azacycloalkyl phosphonates. Compounds of this invention reduce levels of serum cholesterol in the body without significantly reducing mevalonic metabolite synthesis. This invention relates also to pharmacological compositions and method of treatment for lowering serum cholesterol levels using the compounds of this invention.
Synthesis of acyclonucleoside phosphonates as antiviral agents against cytomegalovirus

, p. 539 - 550 (2007/10/02)
Phosphonic acid analogs of ACV and DHPG that are isosteric with ACV phosphate and DHPG phosphate have been synthesized and evaluated for antiviral activity against human, murine, and guinea pig strains of cytomegalovirus. The phosphonates showed high activity against all of the strains. They were also evaluated against a DHPG resistant strain of human cytomegalovirus. Although the activity dropped considerably, significant antiviral activity was still evident.
