S SGold Substrate where R 1 , R 2 = H, methyl, phenyl, 1-naphthyl, or R 1 -R 2 = (un)substituted cyclohexylThe synthesis and stereochemistry of a series of new cyclic disulfides containing (poly)spirane 1,2-dithiolane units are reported. Also included is a study of the self-assembled monolayers (SAMs) of these compounds on a gold surface. The characteristics of the resultant SAMs were determined by IR spectroscopy using molecular mechanics calculations.

in Wiley Online Library (wileyonlinelibrary.com).Natural occurrence, synthesis, chemical behavior, and physical properties of aromatic cyclopenta[c]pyrans are reviewed. Various strategies for the synthesis of cyclopenta[c]pyrans starting from cyclopentadienes, fulvenes, oxadiazinones, or a-pyrones were developed according to the substitution patterns of the target compounds.

Palladium-Catalyzed Carbonylation of (Hetero)Aryl, Alkenyl and Allyl Halides by Means of N-Hydroxysuccinimidyl Formate as CO Surrogate. -The reaction is successfully applied in the synthesis of precursors of known acetylcholinesterase inhibitors, e. g. (VII), that can be easily and quantitatively converted into the agents by quaternization with methyl triflate. -(BARRE, A.; TINTAS, M.-L.; ALIX, F.; GEMBUS, V.; PAPAMICAEL, C.; LEVACHER*, V.; J. Org.
