Addition of lithiated 4,5-dihydro-1,3,5-dithiazines to in situ generated N-silylimines in THF produces 2-(α-aminoalkyl)dithiazines, which rearrange into 3,5-dithia-1-azabicyclo[2.2.1]heptanes upon aqueous workup. These novel bicyclic dithiazines can in turn be lithiated at the position 4 and added to carbonyl compounds.
将锂化的4,5-二氢-1,3,5-二噻唑烷与在THF中原位生成的N-硅基亚胺反应,生成2-(α-氨基烷基)二噻唑烷,这些化合物在水相处理后会重排成3,5-二硫-1-氮杂双环[2.2.1]庚烷。这些新型的双环二噻唑烷可以在4位被锂化,并与羰基化合物反应。
