carbo- and hydroamination processes resulted in the formation of nitrogen-containing benzo-fused rings. In the case of aminoallenes arising from o-phenylenediamine, the regioselectivity of the cyclization step was strongly dependent on the protecting group tethered to the nitrogen atoms, allowing the formation of five- and seven-membered rings.

Exemplary embodiments of the present invention relate to benzoxazines having various N-protecting groups. An R
1
functional group is at least one selected from the group consisting of H and a halogen, an R
2
functional group is at least one selected from the group consisting of H, an amide, or a carbamate, and a Z functional group is at least one selected from the group consisting of a phenyl, substituted phenyl group, methyl, and t-butyl group. The exemplary embodiments provide compounds with benzoxazines having various cleavable protecting groups such as amides and carbamates.
Continued Exploration of Trifunctional Alkyl 4-Chloro-2-diazo-3-oxobutanoates: Streamlined Entry into [1,2,3]Triazolo[5,1-c][1,4]benzoxazines and [1,2,3]Triazolo[5,1-c][1,4]benzoxazepines

o-aminophenols followed by deprotection provided a convenient entry into [1,2,3]triazolo[5,1-c][1,4]benzoxazines, which are of high medicinal importance, as documented in the literature. The same approach applied to N-protected substituted o-(aminomethyl)phenols afforded [1,2,3]triazolo[5,1-c][1,4]benzoxazepines, which are practically unexplored compounds from a medicinal chemistry perspective.

Pd-Catalyzed intramolecular allylic C–H amination of 1,1-disubstituted alkenyl amines with various allylic tethers (X = O, NMs, CH2) was developed. This process allows for the divergent synthesis of 1,3-X,N-heterocycles through a regioselective allylic C–H cleavage and π-allylpalladium formation. Particularly noteworthy is the use of substrates containing a labile allylic moiety and new simple catalytic
