Efforts to improve upon the physical properties and metabolic stability of Aurora kinase inhibitor 14a revealed that potency against multidrug-resistant cell lines was compromised by increased polarity. Despite its high in vitro metabolic intrinsic cleara

This report describes a protocol for functionalization of thiophenes, utilizing a regioselective magnesiation mediated by commercial Grignard reagents and catalytic 2,2,6,6-tetramethylpiperidine. This metalation provides practical access to metallo thiophenes, avoiding cryogenic conditions, prolonged reaction times, and prohibitively expensive reagents. Application to a target thiophene-phthalazinone 6 was accomplished by addition of 2-magnesio-4- methylthiophene to phthalic anhydride, providing the product with >40:1 regioselectivity. This also solved a chemoselectivity issue encountered with analogous lithio-thiophene reagents and cyclic anhydrides, or with magnesio-thiophene generated by simultaneous lithium-to-magnesium transmetalation/anhydride acylation. These alternative in situ transmetalation sequences were plagued by an age effect dictated by the kinetic solubility of MgCl2/THF complexes.
