Popis:	A variety of 2-acyl-, 2-aroyl- and 2-formyl-substituted phenols are converted in a one-pot reaction with α,β-unsaturated carboxylic acid chlorides into the corresponding 3-alkenylcoumarins. Especially the labile 3-vinylcoumarins are readily available by the simple to perform protocol. If longer alkenyl chains are involved in position 3, small molecules with excellent organo gelating properties are established. The mode of action for such aggregates is confirmed by X-ray analysis of an analogue.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
