The present invention describes tetracyclic compounds of formula (IA) or (IB), wherein the symbols R, X, A, Y, R2, R3 and D are as defined in the specification, their use in the treatment of certain diseases, e.g. depending on MK-2 or TNF activity, and ways of manufacturing them.
scientists. Herein, we present a practical and stable heterogeneous copper catalyst, which permits for dehalogenative deuteration via water–gas shift reaction at comparably low temperature. This novel approach allows deuteration of diverse (hetero)aryl halides with good functional group tolerance, and no reduction of the aromatic rings or other easily reducible formyl and cyano groups.
