hydrogenation. These substrates were then exposed to an N-heterocyclic carbene, whereupon intramolecular Stetterreaction proceeded smoothly to give various spirofused tricyclic 1,4-diketones in 30–87% yields. Furaldehyde and nicotinaldehyde derivatives also participated in the reaction under the Stetter conditions.

Here we describe a new class of potent S1PR1 agonists wherein the exocyclic nitrogen was moved away from the pyridine ring (e.g. 11c). Further structural modifications led to the identification of novel alkylaminomethyl substituted phenyl and thienyl derivatives as potent S1PR1 agonists. These new alkylaminomethyl aryl compounds showed no phototoxic potential. Based on their in vivo efficacy and ability

3-Substituted isocoumarins are synthesized in good to excellent yields via palladium catalyzed coupling of 2-(2′,2′-dibromovinyl)benzoates and organostannanes. The process involves a Stille reaction, and a subsequent annulation reaction.
The invention relates to novel aminomethyl benzene derivatives, their preparation and their use as pharmaceutically active compounds. Said compounds particularly act as immunomodulating agents. (I) wherein A represents one of the groups (I), (I), (I) and (I).
