Cu-Mediated Stereoselective [4+2] Annulation between N-Hydroxybenzimidoyl Cyanide and Norbornene
A Cu-mediated stereoselective [4+2] annulation between N-hydroxybenzimidoyl cyanides and norbornene (NBE) has been developed for the synthesis of 4H-1,2-oxazin-4-ones. The reaction proceeds through sequentially forming C-O/C-C bonds. The advantage of this reaction includes high stereoselectivity, excellent yields, as well as simple and mild reaction conditions. A total of 26 examples are presented along with some control experiments.
Synthesis of new dithiolethione and methanethiosulfonate systems endowed with pharmaceutical interest
Here we report synthetic methodology affording in the most efficient way the rapid preparation of new dithiolethiones (DTTs) and methanethiosulfonates (MTSs). These were evaluated as STAT3 inhibitors since these electrophilic systems could react with thio
A convenient synthesis of α-hydroxyiminoacetonitriles from aldoximes
Aromatic α-hydroxyiminoacetonitriles can be conveniently prepared by a facile one-pot procedure in high yields involving chlorination of the corresponding aldoximes with tert-butyl hypochlorite followed by reaction with alkali cyanide.
