Anti-Markovnikov hydroazidation of unactivated alkenes using ABX2014;N3 as an initiator has been developed at room temperature, wherein hydrogen azide (HN3) acts as both hydrogen and azidating agent. Notably, the HN3 reage

The synthetically useful functionalized 2-substituted piperidines containing a lateral ketone group have been strategically accessed via an organocatalytic enantioselective intramolecular aza-Michael addition of enone carbamates, in which a novel internal substrate combination of the enone moiety as Michael acceptor and the carbamate moiety as Michael donor was revealed in asymmetric bifunctional organocatalysis. This heteroatom conjugate addition, which was realized by using a catalytic chiral Cinchona-based primary-tertiary diamine and an achiral Bronsted acid, mostly proceeded in high yield and good to excellent stereocontrol (up to 99% ee). This reaction provides an alternative catalytic asymmetric method for installing the stereogenic nitrogen-containing carbon center in functionalized 2-substituted piperidines, leading to the development of a straightforward and expeditious synthesis of some naturally occurring bioactive 2-substituted piperidine alkaloids.

The total synthesis of (+)-nakadomarin A is described. A three-component cycloaddition of a hydroxylamine, aldehyde, and cyclopropane to form a highly functionalized tetrahydro-1,2-oxazine serves as the foundation for this synthesis. The resulting oxazine

(Equation presented) A one-pot procedure was developed to prepare efficiently alkyl azides from alkanus using bis(2,4-dichlorophenyl) phosphate activation. 4-(Dimethylamino)pyridine was used as a base, and phosphorylpyridinium azide is believed to be the activating agent under this condition.
