The X-ray diffraction data of a bis-iminolactone is described and present an interesting helical column packing.enN-Substituted cyanoacetamideIminolactoneButenolideDiamineBis-iminolactoneBis-lactoneEfficient synthesis of new butenolides by subsequent reactions: application for the synthesis of original iminolactones, bis-iminolactones and bis-lactonesArticle
