Abstract: The present invention relates to a process for the preparation of a chiral prostaglandin enol intermediate of formula 1, comprising the steps of: separating a compound of formula 16-(R,S)-10 into its diastereomers by fractional crystallisation, reducing the 15-oxo group of the compound of formula 16-(R)-10, thereby obtaining a compound of formula 15-(R,S), 16-(R)-11, followed by removing the protecting group of the compound of formula 15-(R,S), 16-(R)-11, and isolating the compound of formula 1, and optionally, crystallizing the compound of formula 1. Optionally, the undesired isomer formed during fractional crystallization can be epimerized and further amount of the desired isomer can be recovered from the resulting mixture. The present invention also provides novel intermediates useful in the process. The invention further relates to a process for fractional crystallization of the compound of formula 16-(R,S)-10.

Abstract: Systems and methods for reconfiguration of illumination products are presented. An illumination product comprises components that implement a device access framework to facilitate access to the configuration of the illumination product by external components. Components internal to or otherwise associated with the illumination product codify various configuration parameters associated with the illumination product in one or more files (e.g., text files) and/or file attributes (e.g., filenames). One or more external components coupled to the internal components use a file access API to read from, write to, and/or otherwise manipulate the files (e.g., modify file content and/or file attributes) so as to access and/or affect the configuration parameters. Changes to the configuration parameters invoked by the external components are detected by the internal components and applied to the configuration (e.g., operational settings) of the illumination product.
