scheme or table, p. 946 - 957 (2011/08/05)
A series of 5-aryl-1,2-dithiolethiones and 5-aryl-1,2-dithiole-3-ones were investigated as hydrogen sulfide-releasing anti-inflammatory drugs. Generally, phenolic acetophenones were best protected by methoxymethyl groups and the dithiolethione group insta

Acylation of 1,n-bis(5-tert-butyl-2-methoxyphenyl)alkanes 6 with acid chloride or acid anhydride in the presence of Lewis acids afforded only the product arizing from two-fold ipso-acylation at the tert-butyl groups; similar reaction of 1,2-bis(5-tert-butyl-2-methoxy-3-methylphenyl)alkanes 8 led only to the recovery of the starting compounds, thus differing from the nitration of 8 with fuming HNO3 at room temperature which affords in quantitative yield the selective ipso-nitration product at the tert-butyl groups.However, the ipso-acylation reactions of 5,13-di-tert-butyl-8,16-dimethoxymeta-cyclophane 15 led to the first-reported direct introduction of an acyl group due to a through-space electronic interaction with the opposing benzene ring.In contrast the selective ipso-acylation reaction was not observed in the case of the larger ring sized macrocyclic meta-cyclophane, p-tert-butyltetramethoxycalix(4)arene.
SIGMATROPIC REARRANGEMENT OF ARYLHYDRAZONES FOLLOWED BY 1,2-SHIFT OF AN ARYL GROUP. VII
Sannicolo, Franco
, p. 91 - 96 (2007/10/02)
Arylhydrazones of ethyl 4-methoxy-3,5-dimethylphenylglyoxylate and 4-methoxy-3,5-dimethylacetophenone rearrange in hot polyphosphoric acid to give biphenyl derivatives arising from a sigmatropic rearrangement followed by an aryl group 1,2-shift.Stru
