4-dienylamines (10). The kinetics of these reactions have been investigated and an explanation of substituent effects is advanced. Also a new route to m-hydroxybenzoicacids has been established by cyclisation of substituted hexa-3,4:5,6-dienoic acids.
An improvement of a known two step cyclization procedure affording 4-aryl-3-hydroxy benzoic acid derivatives from 3-aryl-2,3-unsaturated aldehydes and dimethyl succinate is described. The high versatility of the synthetic procedure is shown as the aryl substituent can be a benzene or naphthalene moiety or an heteroaromatic ring. It can be applied iteratively to prepare p,p-oligophehyl derivatives. (C) 1997 Elsevier Science Ltd.
