Thomson Group

Examples of three different oxidant-promoted iV-allylic hydrazone rearrangements developed by the Thomson group are illustrated in Scheme 14.19a. These transformations convert N-allylic hydrazones to homoallylic halides in the presence of either CUCI2 or NBS and to... 

The Thomson group has also recendy adapted the iodonium-promoted rearrangement of N-allylic hydrazones to the synthesis of several naphthyl-type lignan natural products that display... 

Heterocyclic compounds carrying hydroxyl groups may be compared with phenols. Thomson has reviewed the tautomeric behavior of phenols often both tautomeric forms of polycyclic compounds such as naphthols can be isolated. Early work on hydroxy-thiophenes and -furans was also reviewed by Thomsond but until recently their chemistry has been in a somewhat confused state. A pattern is now beginning to emerge, at least for the a-substituted compounds, which appear to exist as A -oxo derivatives and to attain equilibrium slowly with the corresponding A -oxo forms. For the a-hydroxy compounds, the equilibrium generally favors the A -oxo form.

Of the experiments performed in animals, none has shown death from inhalation exposure to aluminum or its compounds. For example, no deaths were reported following an acute 4-hour exposure to up to 1,000 mg Al/m3 as aluminum oxide in groups of 12-18 male Fischer 344 rats (Thomson et al. 1986) or...
