This joint paper between Shasun Pharma Solutions and ABB outlines some of the challenges associated with hazardous batch process safety assessment and the benefits from carrying out a systematic study. Historically, Layer of Protection Analysis (LOPA) had been tried, bul was found to be inadequate for the situation. Shasun Pharma Solutions had relocated an exothermic batch reactor process to its site near Cramlington, Northumberland. In the relocation, a number of changes and improvements had been made to the process, so that the arrangements were not identical to those in the previous operating location. Therefore previous safety assessments were no longer applicable to the project. Dudley Northumberland is top tier COMAH site and Shasun had a legal obligation to ensure that the safeguards proposed reduced the individual risk of operating the new process to ALARP whilst also complying with the site's overall risk criteria. In doing so, Layer of Protection Analysis was tried but the challenges presented by the process led to the rejection of this method by the company and a lack of confidence in the results by the regulator. The alternative approach as described in this paper, builds on some of the guidance from the post-Bunce field PSLG report, applies it to the batch processing pharmaceuticals sector, and couples it with a more flexible assessment technique. This paper highlights the benefits of the approach used, and more importantly that it is applicable to all parts of the process sector, not just pharmaceuticals. © 2012 ABB Consulting and Shasun Pharma Solutions.

The applications of the most recently developed asymmetric Diels-Alder (D-A) reactions, [n + m] cycloaddition reactions, molecular rearrangements, free-radical reactions and transition-metal-catalyzed cyclization reactions toward the syntheses of APIs and natural products with bridge-containing ring systems were studied. The Diels-Alder cycloaddition reaction is one of the most fundamental synthetic transformations and has been the cornerstone in countless total syntheses. Lewis-acid-catalyzed asymmetric DA reactions have attracted great attention due to their ability to construct complex carbocyclic frameworks. 2,5-disubstituted cyclopentadiene is highly competent in Diels-Alder cycloadditions with a wide variety of dienophiles under very mild reaction condition. A combination of intramolecular Diels-Alder cycloaddition with intermolecular Diels-Alder cycloaddition, developed by Baran's group, constitutes a powerful tool to access a key tricyclic carbon skeleton.
