  • Amphiphilic Janus-dendrimers
    Patent number: 9623046
    Abstract: The invention concerns compounds of the formula: X—(Y)t wherein: X is Formula (X), each Y is the same or different and is Formula (Y) —O—[CH2—CH(OH)—CH2—O—]m—H; or —C(OR5)3; R1, R2, R3, R6, R7, R8, R9, R10 are each, independently, —(CH2CH2O)m—R4, —[CH2CH(OH)CH2O]nH, OR11, —O(CH2)PR13, or —(CH2)R12; each R4 is independently OR5 or OH; R5, R11 and R12 are each, independently, H or C1-C30 alkyl; R13 is —NH3+Cl? or —NHBoc; t is an integer from 2 to 6; m, n, and p are each, independently, an integer from 1 to 12; and each q, r, and s is 0 or 1 and the sum of q+r+s is at least 2.

  • Processes for the preparation of biphenyl compounds
    Patent number: 8530689
    Abstract: The invention concerns processes for the synthesis of a compound of the formula: wherein: R1 and R2 are each, independently, C1-C12 alkyl, CO2R3, OR4, R5(OR6), or C6-C18 aryl; R3-R6 are each, independently, C1-C12 alkyl or C6-C12 aryl; and n and m are each, independently, O or an integer from 1-5; said process comprising:—contacting a compound of the formula H0-R7-0H with BH3 and a compound of the formula in the presence of a nickel-containing catalyst to produce a first product, where R7 is a C2-C12 hydrocarbon group and X is a halogen, OMs or OTs;—contacting the first product in situ with a compound of the formula: in the presence of a nickel-containing catalyst to produce a compound of formula I, where Z is a halogen.
