Patent number: 8822679Abstract: A compound useful as a building block for the manufacture of various compounds is represented by Formula A or D. In Formula A and D, z is 0 or 1; Q is a heteroatom; R1 through R11 and Ra through Rf are each independently hydrogen, a substituted or unsubstituted hydrocarbyl group, a substituted or unsubstituted heteroatom containing hydrocarbyl group, or a functional group; d, e and f are each independently 0 or greater; each of A, B and D is independently a carbon atom or a heteroatom; and two or more of R1 though R11, Ra through Rf and Y optionally combine to form a ring. In some embodiments, R8 and R9 combine to form a carbonyl group. In some embodiments, R2 and Y combine to form a ring with the Q atom. In some embodiments, the ring includes at least one double bond.Type: GrantFiled: June 22, 2012Date of Patent: September 2, 2014Assignee: California Institute of TechnologyInventors: Brian M Stoltz, Scott C.

Publication number: 20060265320Abstract: A system and methods for processing and charting security exchange trading and market information shows security traders if current transactions originated as buy orders (810) or sell orders (812), and simultaneously indicates traded quantity. Security exchange trading information is received including price, volume and time of each trade. Market information is also received including bids and offers. The security exchange trading and market information is processed simultaneously and displayed as a continuously updated realtime chart (800) depicting the exchange auction process. The chart (800) is formed by plotting each trade at the price traded, and for each plot point shows a distinctive icon indication whether the transaction was initiated by a buyer (810) or seller (812).Type: ApplicationFiled: May 3, 2006Publication date: November 23, 2006Applicant: Trading Technologies International, Inc.Inventor: Douglas Duquette
