Intramolecular Azide−Alkyne Cycloaddition for the Fast Assembly of Structurally Diverse, Tricyclic 1,2,3-Triazoles
摘要:
The synthesis of novel tricyclic 1,2,3-triazoles starting from cyclic epoxides via the sequential azidolysis, propargylation and 1,3-dipolar cycloaddition is described. Derivatization by N-arylation reaction and the synthesis of enantiomerically pure compounds is also reported. Some of these compounds exhibit significant affinity for the sigma-1 receptor.
The present invention relates to new tricyclic triazolic compounds having a high affinity for sigma-1 receptor as well as to the process for the preparation thereof, to composition comprising them and to their use as medicaments according to compounds of formula (I), Wherein R1 and R2 are as defined in the description.
