  • Patent number: 9973573
    Abstract: Reducing concurrency in a system comprising a plurality of services sending a plurality of concurrent requests to a back-end service through a concurrency reduction service. The concurrency reduction service maps each concurrent incoming request to a key; and determines if the key to which the concurrent incoming request is mapped matches a key mapped from another concurrent incoming request from the plurality of concurrent requests. If the key to which the concurrent incoming request is mapped matches a key mapped from at least one other concurrent incoming request from the plurality of concurrent requests, then the service groups the concurrent incoming request with the at least one other concurrent incoming request to be sent to the back-end service. The concurrency reduction service sends one outgoing request to the back-end service for each of the keys to which the plurality of concurrent incoming requests were mapped.

  • Publication number: 20120053350
    Abstract: 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 ?-lactamase inhibitors.
