The invention is concerned with novel bicyclic compounds of formula (I), wherein A, L, E, F, G, R1, R2, R3, R4, R5, R6, R7, V, W and n are as defined in the description and in the claims, as well as physiologically acceptable salts thereof. These compounds are antagonists of CCR2 receptor, CCR5 receptor and/or CCR3 receptor and can be used as medicaments.
A rapid and atom economical multicomponent synthesis of complex aza-diketopiperazines (aza-DKPs) driven by Rh(I)-catalyzed hydroformylation of alkenylsemicarbazides is described. Combined with catalytic amounts of acid and the presence of nucleophilic species, this unprecedented multicomponent reaction (MCR) enabled the formation of six bonds and a controlled stereocenter from simple substrates.
