A catalytic highly enantioselectivesynthesis of spirooxazolines is presented. Starting from readily available 2-naphthol-substituted benzamides and using catalytic amounts of a chiral triazole-substituted iodoarene catalyst, a variety of spirooxazolines can be isolated through an enantioselectiveoxidativedearomatization in up to 92% yield and 97% ee. The further synthetic utility of the optically

Contained chirality: Novel binaphthyl-based chiralhypervalentiodine(III) reagents are presented with the chirality contained only in the ligand. These have been characterized by X-ray analysis, and all derivatives show the prominent reactivities of hypervalentiodine reagents. Due to their limited stability in solution, they are inefficient chiraliodine(III) derivatives.
包含手性:新型基于联萘的手性高价碘(III)试剂具有仅包含在配体中的手性。这些已通过 X 射线分析进行了表征,并且所有衍生物都显示出高价碘试剂的突出反应性。由于它们在溶液中的稳定性有限,它们是低效的手性碘 (III) 衍生物。
Synthesis of 1-Amidoalkyl-2-Naphthols by Two-Component Friedel-Crafts Reaction

日期:——
A one-pot two-component Friedel-Crafts reaction of 1-amidoalkyl-2-naphthols by the condensation of 2-naphthol with various N-methyl hydrocarbon unsaturated amides in presence of the concentrated sulphuric acid as catalyst and anhydrous ethyl alcohol as solvent to form the corresponding amidoalkyl naphthols is described. This procedure offers advantages such as eco-friendly, shorter reaction times, simple work-up, excellent yields and recovery and reusability of the catalyst. The spectroscopic properties are assessed for their effectiveness and the fluorescent intensity sequence of three compounds in two different solvents follows the sequence: 1-N-methacrylamide-2-naphthol > 1-N-methy phthalimide-2-naphthol > 1-N-methy phthalimide-2-naphthol.
