The disclosure describes chiral P(V)-based reagents and their uses for the modular, scalable, and stereospecific synthesis of chiral phosphines, phosphine oxides and particular oligonucleotides.

The present invention relates to a series of novel multifunctional mono- and bis-acylphosphine oxides, which are useful as photoinitiators, and to photocurable compositions comprising said photoinitiators.

A photoinitiator selected from the group consisting of an acylphosphine oxide, a α-hydroxy-ketone and a α-amino-ketone, characterized in that the photoinitiator includes at least one aliphatic disulfide as functional group.

The present invention provides a phosphorus-containing compound characterized by being a compound represented by the following structure: ##STR00001## the compound is a novel immune cell migration inhibitor. The compound has good hydrophilicity and can be developed into eye drops. The compound has a strong inhibitory ability to immune cell migration and can relieve the symptoms of most dry-eye patients.

The present invention relates to a novel synthesis method to form particular molecules. These molecules have multiple uses, most notably in the field of protecting groups used throughout organic and synthetic chemistry. The disclosed method is safer, more cost- and time-effective, and more amenable to large scale production than those currently known in the art. The protecting groups synthesized are useful in GAP peptide synthesis.
