Pyrimido[4,5-b]indole derivatives are provided. These compounds are useful to expand hematopoietic stem cell populations, particularly, human hematopoietic stem cell populations. The compounds are also useful in the medical treatment of diseases that involve hematopoietic stem cells.
The first example of tetrazole‐directed meta‐selective C−H nitration is described. This transformation provided a straightforward approach for the synthesis of biologically important m‐nitroaryltetrazoles in moderate to excellent yields with good functional group compatibility. In addition, new metallo‐β‐lactamase inhibitors were obtained by further transformation of the synthesized m‐nitroaryltetrazoles

Rh(III)-catalyzed direct olefination reaction via aromatic C–Hbondactivation is described using tetrazole as the directinggroup. This reaction provides a straightforward way for the synthesis of ortho-alkenyl aryl tetrazoles. Various functional groups tolerate the reaction conditions and afford the corresponding products in moderate to excellent yields.

An efficient one-pot ZrO2 nanoparticles-supported Cu2(II)-β-cyclodextrin promoted [2+3] cycloaddition of benzonitriles and sodium azide followed by post tetrazole alkylation using aralkyl esters for the synthesis of N-2-substituted tetrazoles has been presented. One-pot operation, atom-economical, regioselectivity and good yields are the main advantages of this protocol. From the atom economy, it is clear that, catalyst can be reused up to four times without any appreciable changes in catalytic activity
