  • Phosphorus-containing compounds & uses thereof
    Publication number: 20070190106
    Abstract: This invention concerns a new family of phosphorus-containing compounds containing a moiety JQA- in which: A is absent or is —O—, —S— or —NR2—; Q is absent or (if A is —O—, —S— or —NR2—) Q may be —V—, —OV—, —SV—, or —NR2V—, where V is an aliphatic, heteroaliphatic, aryl, or heteroaryl moiety, such that J is linked to the cyclohexyl ring directly, through A or through VA, OVA, SVA or NR2VA; K is O or S; each occurrence of Y is independently —O—, —S—, —NR2—, or a bond linking a R5 moiety to P; each occurrence of R2 and R5 is independently an aliphatic, heteroaliphatic, aryl, or heteroaryl moiety, or H; and each occurrence of R6 is independently —PK(YR5)(YR5), —SO2(YR5) or —C(O)(YR5); so long as any R2, or R5 moiety linked directly to P is not H; wherein two R2, R5 and/or R6 moieties may be chemically linked to one another to form a ring; each occurrence of G is independently —O—, —S—, —NR2— or (M)x; each occurrence of M is independently a substituted or unsubstituted methylene moiety, and any M-M? moie
