Chiral five-membered ring 2-oxazolidinones and six-membered ring 1,3-oxazinan-2-ones are synthesized from the corresponding amino alcohols with complete inversion or retention of stereochemistry. Chiral 5-substituted 2-oxazolines and 6-substituted 2-oxazines are also synthesized from the same starting materials with inversion of stereochemistry through an intramolecular SN2 reaction. These compounds
由相应的氨基醇合成具有手性的五元环2-恶唑烷酮和六元环1,3-恶二酮-2-酮,并完全反转或保留立体化学。手性5-取代的2-恶唑啉和6-取代的2-恶嗪也从与立体化学的反转相同的原料合成,通过分子内小号Ñ 2反应。这些化合物是有机合成中有用的中间体,是许多药物化合物的重要组成部分。
