One pot synthesis of aryl substituted aurones

7-Methoxyindan-1-one

“…For the preparation of the title compound, see: Li et al (2011). For applications of indanone derivatives, see: Borge et al (2010); Cai et al (2005); Cui et al (2009); Fu & Wang (2008); Li et al (2009); Sousa et al (2011); Tang et al (2011). For related structures, see: Ali et al (2010a,b,c,d); Chen et al (2011a,b).…”

“…Indanone and its derivatives are some of the most widely used organic compounds (Tang et al, 2011). They are used as dyes and pigments (Cui et al, 2009;Li et al, 2009), intermediates in organic synthesis (Fu & Wang, 2008;Borge et al, 2010) and exhibit a wide variety of biological activities (Sousa et al, 2011). In addition, 1-indanones were important precursors in the regiospecific synthesis of 2-fluoro-1-naphthols (Cai et al, 2005).…”

A Facile One Pot Synthesis of Substituted Pyrazole Derivatives

“…18 Thus we achieved our first aim of reacting the diaryldiazomethanes 2a-c with compounds 3a-c to access the spiropyrazolinic skeleton 4a-i, but, the unexpected products 5a-i were obtained. Structures were assigned on the basis of their spectral data and are new pyrazoles (Scheme 1).…”

Synthesis of New Spirocyclopropane and Oxadiazole Products

“…In the second part of our work, we were prompted to investigate the reactivity of the ( Z )‐2‐arylidene‐benzofuran‐3(2H)‐ones 6a , 6b , 6c , 6d , prepared according to the literature procedure , with 2‐diazopropane 2 . Indeed and owing to the fact that the reactions of ( Z )‐2‐arylidene‐benzofuran‐3(2 H )‐ones 6a , 6b , 6c , 6d with diazoalkanes have been well studied over the last few years , the treatment of compounds 6a , 6b , 6c , 6d with an excess of 2 at 0°C in dry dichloromethane afforded the spirocyclopropane 7a , 7b , 7c , 7d (Table ).…”
