Early process development toward the scalable production of taxadienone on a decagram scale is described. A continuous flow reactor was employed to safely run a potentially hazardous cyclopropane ring opening. The route featured two copper-mediated a

The aromatic amine in fluoroanilines was protected with 2,2,5,5-tetramethyl-1-aza-2,5-disila-cyclopentane (stabase) in order to direct metalation ortho to the fluorine. A series of novel 2-fluoro-3-aminophenylboronates were prepared after quenching t

A novel N,N-diisopropylformamidine (DIFA) protecting group for anilines was studied. Metalation is often metal-directed by this weakly coordinating and bulky group, making it complementary to ortho-metalation directed by tert-butylcarbamate and pival

[reaction: see text] The concecutive Criegee rearrangement reactions were studied for tert-butyl trifluoroacetate, triarylcarbinols, and benzophenone ketales with trifluoroperacetic acid (TFPAA) in trifluoroacetic acid (TFA). The formation of methyl

Carboxonium ions were studied through analysis of the bonding situation in terms of natural bond order, natural resonance structure contributors and charges. The stabilizing effect of oxygen was also elucidated through hydride exchange reactions and
