  • Patent number: 9112226
    Abstract: An anode material for ultrafast-charging lithium ion batteries, the anode material comprising C—Li4Ti5O12. A method of synthesizing an anode material for ultrafast-charging lithium ion batteries, the method comprising the steps of: adding lithium to an organic alcohol to form a first solution; adding titanium via an organic titanium source to the first solution to form a second solution; adding water to the second solution to form a diluted second solution; heating the diluted second solution at a temperature ranging from about 80° C. to about 180° C. to obtain solid Li4Ti5O12; and annealing the solid Li4Ti5O12 in the absence of air to obtain the anode material comprising C—Li4Ti5O12.

  • Patent number: 8304553
    Abstract: A process is provided for the synthesis of 4,5-diamino cyclohexene carboxylate ester (1): or a pharmaceutically acceptable salt thereof. R1-R3 are a silyl-, an aliphatic, alicyclic, aromatic, arylaliphatic, or an arylalicyclic group. R4, R11 and R12 are H, a silyl-group, an aliphatic, alicyclic, aromatic, arylaliphatic, or an arylalicyclic group. 3,4-Dihydropyran compound (9): with R5 and R6 being suitable protecting groups, is reacted to form aldehyde (4): which is oxidized and converted to N-substituted carbamate (3): with R7 being a suitable protecting group. (3) is, via oxazolinidone (13): converted to azido carboxylate ester (2): and then to 4,5-diamino cyclohexene carboxylate ester (1).
