T1  - A novel photorearrangement of (coumarin-4-yl)methyl phenyl ethers
N2  - In the present study, we describe synthesis and photochemical behaviour of the coumarinylmethyl phenyl ethers 1 and 6-10. Irradiation of the compounds in polar solvents leads to o-, p- and m-hydroxybenzyl substituted coumarins as main products. A side reaction is the photosolvolysis of the ethers that gives the (coumarin-4-yl)methyl alcohol and the corresponding phenol. Detailed studies of the quantum yields and product distributions upon irradiation of 6 as a function of the solvents are indicative of a dominant role of an ionic pathway in photochemical conversions. The found photochemical rearrangement is a useful tool for the preparation of hydroxylated 4-benzylcoumarins. A series of such compounds have been synthesised.

T1  - Molecular rods with oligospiroketal backbones as anchors in biological membranes
N2  - Getting stuck in: A hydrophobic molecular rod with terminal fluorescent moieties has been synthesized. The insertion of the rod into membranes was investigated and shown to incorporate efficiently into model and biological membranes (see picture; gray C, blue N, red O). Those rods can be used as stable membrane-associated anchors for functionalization of membrane surfaces.
