Herein, we report the synthesis and structure-activity relationship studies of new analogs of boceprevir 1 and telaprevir 2. Introduction of azetidine and spiroazetidines as a P2 substituent that replaced the pyrrolidine moiety of 1 and 2 led to the disco

The present invention relates to a process for the stereoselective preparation of a compound having the general formula (I) or its respective diastereomers: comprising reacting a compound having the general formula (II) or its diastereomers: with a compound of the general formula III: R3-COOH and a compound of the general formula IV: R4-NC wherein R1 represents each independently, or jointly a substituted or unsubstituted alkyl, alkenyl, alkynyl, aromatic or non-aromatic, mono-, di- or tricyclic, or heterocyclic structure, and R2 represents a hydrogen atom, a substituted or unsubstituted alkyl, alkenyl, alkynyl, aromatic or non-aromatic, mono-, di- or tricyclic, or heterocyclic structure, and R3 represents a substituted or unsubstituted alkyl, alkenyl, or alkynyl, or an aromatic or non-aromatic aromatic or non-aromatic, mono-, di- or tricyclic, or heterocyclic structure.

A very short and efficient synthesis of the important drug candidate telaprevir, featuring a biocatalytic desymmetrization and two multicomponent reactions as the key steps, is presented. The classical issue of lack of stereoselectivity in Ugi- and Passerini-type reactions is circumvented. The atom economic and convergent nature of the synthetic strategy require only very limited use of protective groups.
