标 题:Synthesis of functionalized macrocycles by ring closing metathesis

权利人:STUDIENGESELLSCHAFT KOHLE MBH
摘要:The invention concerns an improved process for the preparation of macrocyclic products with 12 or more ring atoms containing one or more polar functional groups on the ring and/or one or more heteroatoms within the ring by ring closing metathesis (RCM) of suitably substituted diene precursors even if the substrates are devoid of any kind of conformational preorganization. Metal carbene complexes of Ru, Mo, W, Re, Os, which are tolerant towards the respective functional group and can either be isolated or prepared in situ are used as catalysts or catalyst precursors. Preferred catalysts or catalyst precursors are ruthenium complexes of the general type XX1LL1Ru=CRR1, wherein X, X1=halogen, L, L1=trialkylphosphine, R, R1=H, Ph, CH=CPh2 denote the most preferred embodiment. The process can be applied to the synthesis of olfactory compounds, perfumary ingredients, pheromones, crown ethers, antibiotics and pharmaceuticals for human and veterinary medicine.

标 题:Polyester synthesis
发明人：WOSNICK JORDAN H
权利人:XEROX CORP
摘要:The present disclosure provides for enzymatic polymerization to produce polyester resins suitable for use in manufacturing toners. In embodiments, crystalline copolymers, which are polyesters, may be synthesized from lactones, cyclic anhydrides, cyclic carbonates, and combinations thereof. These crystalline copolymers, in turn, may be utilized in the synthesis of toner particles.

标题 :Zero-copy sparse matrix factorization synthesis for heterogeneous compute systems
发明人：THUERCK DANIEL; WEBER NICOLAS
权利人:NEC Laboratories Europe GmbH
摘要:A system, method, and computer-readable medium for synthesizing zero-copy sparse matrix factorization operations in heterogeneous compute systems are provided. The system includes a host and an accelerator device. The host device is configured to divide an input matrix into a plurality of blocks which are transferred to a memory of the accelerator device. The host device is also configured to generate at least one index buffer that includes pointers to the block in the accelerator's memory, where each index buffer represents a frontal matrix associated with a matrix decomposition algorithm. The host processor is configured to receive one or more kernels configured to process the index buffer(s) on an accelerator device. The index buffers are processed by the accelerator device and the modified block data is written back to a memory of the host device to generate a factorized output matrix.
