  摘要：

  Oxadisilole-fused-3,4-dihydro-2H-naphtho[2,1-e]-1,3-oxazines and 3,4-dihydro-2H-anthra[2,1-e]-1,3-oxazines were synthesized through an eco-friendly Mannich type condensation-cyclization reaction of oxadisilole-fused-1-naphthalenol or 1-anthracenol with formaldehyde and primary amines at ambient temperature in high to excellent yields. The photophysical, electrochemical, and thermal properties of these 3,4-dihydro-2H-anthra[2,1-e]-1,3-oxazine derivatives were also studied. (C) 2013 Elsevier Ltd. All rights reserved.

• Highly efficient synthesis of extended triptycenes via Diels–Alder cycloaddition in water under microwave radiation

  Microwave-irradiated Diels–Alder reactions of anthracene and endoxides (6a–g) in water afforded the cycloadducts (8a–g) with high efficiencies. The extended triptycenes (2a–g) were readily obtained by dehydration of 8a–g in a mixture of AcOH and Ac2O with good overall yields.

  微波在水中与蒽和内氧化物（6a – g）的Diels–Alder反应使环加合物（8a – g）具有较高的效率。通过在AcOH和Ac 2 O的混合物中将8a – g脱水，可以轻松获得扩展的三联体（2a – g），且总收率良好。
