Publication number: 20160016891Abstract: This invention provides a convenient method for converting oximes into enamides. The process does not require the use of metallic reagents. Accordingly, it produces the desired compounds without the concomitant production of a large volume of metallic waste. The enamides are useful precursors to amides and amines. The invention provides a process to convert a prochiral enamide into the corresponding chiral amide. In an exemplary process, a chiral amino center is introduced during hydrogenation through the use of a chiral hydrogenation catalyst. In selected embodiments, the invention provides methods of preparing amides and amines that include the 1,2,3,4-tetrahydro-N-alkyl-1-naphthalenamine or 1,2,3,4-tetrahydro-1-naphthalenamine substructure.Type: ApplicationFiled: May 18, 2015Publication date: January 21, 2016Inventors: Hang ZHAO, Stefan G. Koenig, Charles P. Vandenbossche, Surendra Singh, Harold Scott Wilkinson, Roger P. Bakale

Publication number: 20160014393Abstract: A time-of-flight camera images an object around a corner or through a diffuser. In the case of imaging around a corner, light from a hidden target object reflects off a diffuse surface and travels to the camera. Points on the diffuse surface function as a virtual sensors. In the case of imaging through a diffuser, light from the target object is transmitted through a diffusive media and travels to the camera. Points on a surface of the diffuse media that is visible to the camera function as virtual sensors. In both cases, a computer represents phase and intensity measurements taken by the camera as a system of linear equations and solves a linear inverse problem to (i) recover an image of the target object; or (ii) to compute a 3D position for each point in a set of points on an exterior surface of the target object.Type: ApplicationFiled: July 9, 2015Publication date: January 14, 2016Applicant: Massachusetts Institute of TechnologyInventors: Achuta Kadambi, Hang Zhao, Boxin Shi, Ayush Bhandari, Ramesh Raskar
