Recent advances in aza Friedel–Crafts reaction: strategies for achiral and stereoselective synthesis

A stereoselective synthesis of (+)-physoperuvine using a tandem aza-Claisen rearrangement and ring closing metathesis reaction.

A stereoselective synthesis of (+)-physoperuvine, a tropane alkaloid from Physalis peruviana Linne has been developed using a one-pot tandem aza-Claisen rearrangement and ring closing metathesis reaction to form the key amino-substituted cycloheptene ring.

Recent Advances in Hemophilia Gene Therapy

Heterogeneous loss of function mutations at F8 and F9 genes causes X-linked recessive bleeding disorders, hemophilia A (HA) and hemophilia B (HB), respectively. HA is clinically indistinguishable from HB and accounts for more than 80% of hemophilia cases; the former affects 1/5000 and the latter 1/25000 male births worldwide. In Iran, it is estimated that around 4300 HA and 900 HB patients are ...

An Efficient Protocol for the Synthesis of Carboacyclic Nucleosides via Aza-Conjugate Addition Reaction

A new efficient method for the synthesis of carboacyclic nucleosides as biologically interesting compounds via aza-conjugate addition of pyrimidine nucleobases to a,β-unsaturated esters in the presence of catalytic amount of LiOH.H2O (1.2-4.8 mol%) under microwave irradiation is described. This method affords the title compounds in good to excellent yields and i...

Synthesis, characterization and using Fe3O4@SiO2@FeCl3 as a new nanocatalyst for aza-Michael reaction between amines and ethyl crotonate

In this article, recyclable Fe3O4@SiO2@FeCl3 was synthesized and entirely characterized by various techniques including XRD, FT-IR, SEM, EDX and VSM analysis. The catalytic ability of produced Fe3O4@SiO2@FeCl3 was studied in the aza-Michael reaction of diethyl amine and ethyl crotonate which lead to high yie...
