Synthesis of the first representatives of 3-ethynyldiaziridines
Abstract
1,2-Dimethyl-3-(3,3-diethoxypropyn-1-yl)- and 1,2-dimethyl-3-(3-hydroxymethyl-3-methylbutyn-1-yl)diaziridines have been synthesised by the interaction of 4,4-diethoxybutyn-2-al and 4-hydroxymethyl-4-methylpentyn-2-al, respectively, with equimolar amounts of MeNH2 and MeNHCl (or MeNHOSO3H) at pH 9.5–10; the use of an excess of an
