TLDR
In this article, the regioselectivity of cycloaddition reactions of trichloronitrosomethane with 2-alkyl and 2-aryl was investigated.Abstract:
The regioselectivity of cycloaddition reactions of trichloronitrosomethane (1) with 2-alkyl (R = Me, Et, i-Pr, t-Bu, CF3, Bz, and Cl) and 2-aryl (Ar = Ph, 4-CH3OPh, 4-CH3Ph, 3-CH3Ph, and 4-ClPh) 1,...read more

Synthesis and reactivity of α-allenylhydroxylamines: a new efficient access to 3,6-dihydro-1,2-oxazines
TL;DR: In this paper, the reduction of α-allenyl nitro derivatives using controlled conditions provides either 3-amino-4-vinyl-idenetetetrahydrofuran 3a or 3-hydroxylamino- 4-VINET-THRYFD 4b, f, which undergo intramolecular cyclization consistent with a reverse Cope elimination to afford 3,6-dihydro-1,2-oxazines 5b,f.
