For the first time a one step direct conversion of aromatic hydrazines and azo compounds to N-(tert-butoxycarbonyl) amines is achieved via reductive cleavage of N-N and N=N bonds using the inexpensive and safe hydride source polymethylhydrosiloxane (PMHS) and di-tert-butyl dicarbonate [(Boc)2O] in the presence of a catalytic amount of 10% Pd-C.
Disclosed are methods of identifying, generating and synthesizing compounds that inhibit MAPK13 activity. In various embodiments, compounds, salts thereof and prodrugs thereof of the present teachings can be useful for the treatment of diseases and disorders that involve excess mucus production.

日期:——
development of a method for the Pd(II)-catalyzed denitrogenative coupling of arylhydrazines to give functionalized biaryls in good yield, using aryl bromides or aryl iodides as convenient and inexpensive aryl sources, is reported. High functional group tolerance is demonstrated for electronically distinct arylhydrazines as well as arylhalides. The desired products were isolated in good to excellent yields
