摘要:
A process for the preparation of alkyl esters of N-protected oxo-azacycloalkylcarboxylic acids of Formula III: comprises contacting a ketosulfoxonium ylide of Formula II: with an iridium catalyst to obtain Compound III, wherein PG1 is an amine protective group; k is 0, 1, or 2; and RU, R1, R2, and R3 are defined herein. An embodiment of the process further com rises contacting a compound of Formula I: with a sulfoxonium halide of formula (RU)3S(O)Z, wherein Z is halide, in the presence of a strong base to obtain Compound II. Additional embodiments add a series of process steps leading to the synthesis of 7-oxo-1,6-diazabicyclo[3.2.1]octanes suitable for use as β-lactamase inhibitors.
摘要:
The present invention is directed to a novel process for the preparation of the compound N-[1(R)-[(1,2-dihydro-1-methanesulfonyl-spiro[3H-indole-3,4'-piperdin]-1'-yl)carbonyl]-2-(phenylmethyl-oxy)ethyl]-2-amino-2-methyl-propanamide, and salts thereof, which has the structure: ##STR1## and which has the ability to stimulate the release of natural or endogenous growth hormone. This compound may be used to treat conditions which require the stimulation of growth hormone production or secretion such as in humans with a deficiency of natural growth hormone or in animals used for food or wool production where the stimulation of growth hormone will result in a larger, more productive animal.

Under one aspect, a method of making a superconductor wire includes providing an oxide superconductor layer overlaying a substrate; forming a substantially continuous barrier layer over the oxide superconductor layer, the barrier layer including metal; depositing a layer of metal particles over the barrier layer, said depositing including applying a liquid including metal particles over the barrier layer; and sintering the layer of metal particles to form a substantially continuous metal layer over the barrier layer. In one or more embodiments, the oxide superconductor layer is oxygen-deficient, and the method may include oxidizing the oxygen-deficient oxide superconductor layer. At least a portion of the sintering and the oxidizing may occur simultaneously, for example by performing them at an oxygen partial pressure and a temperature sufficient to both sinter the metal particles and to oxidize the oxygen-deficient oxide superconductor layer.

The method for treating seeds includes combining a seed treatment, a foaming agent, and a solvent to form a seed treatment composition. The seed treatment composition is foamed to form a foamed seed treatment composition. The foamed seed treatment composition is applied to the seed to form at least one treated seed. The treated seed includes a seed and a seed treatment composition applied to the seed. The seed treatment composition includes at least one seed treatment, a foaming agent, and a solvent. The seed treatment composition preferably also includes a polymer or binder.

A plastics waste processor is provided for efficiently compacting and melting plastics waste, so as to form easily disposable compact plastic units having a volume considerably smaller than the unprocessed plastics waste. The plastics waste processor has a waste containment chamber, a rotating chamber door, a jam breaker bar to facilitate opening of the door when jammed by melted plastic waste, pneumatically driven waste compaction means with plastic shedding rams, a waste containment chamber heating system, a processor temperature monitoring means, a cooling means, and a control means. Further a cable and hose management system is provided for protection of moving cables and hoses, as well as a washdown system for automatic cleaning of the processor.
