The term “ rearrangement ” is more general than “isomerization” but for the reactions under photochemical rearrangement will not be concerned with a distinction between these terms.
The Brook Rearrangement Request PDF - ResearchGate
In organic chemistry the Brook rearrangement refers to any [1,n] carbon to oxygen silyl migration. The rearrangement was first observed in the late 1950s by Canadian chemist Adrian Gibbs Brook (1924–2013), after which the reaction is named. These migrations can be promoted in a number of different ways, including thermally, photolytically or under basic/acidic conditions. In the forward direction, these silyl migrations produce silyl ethers as products which is driven by the st… In summary, we have identified a novel class of photoaffinity warheads with short irradiation times capable of generating α-siloxy carbene intermediates suitable for photoaffinity labeling applications at long UV wavelengths in both cell lysate and with pure protein. Further studies are underway to better … See more Identifying drivers of on- and off-target phenotypic responses to bioactive small molecules remains a significant challenge in the field of drug discovery, particularly for low-affinity or low … See more The experimental data, including procedures and characterization data, have been uploaded as part of the ESI.† See more We began by synthesizing a probe that contained an alcohol as a modular site of attachment for conjugation to a small molecule of interest and an alkyne handle, which could be used for either pull-down experiments or … See more F.
