A new, efficient, and simple method for the synthesis of thiiranes from epoxides under solvent-free conditions

A Convenient Synthesis of Highly Substituted Furans by Microwave Irradiation of Ring-Fused Alkylidenecyclopropanes

“…On the other hand, ten minutes microwave irradiation of 1a in o-xylene resulted in a quantitative recovery of 1a (entry 2), while a similar microwave reaction in DMSO instead of o-xylene gave 2a in 20% yield, along with 75% of 1a (entry 3). We next tried to use a solid support such as acidic alumina, 18 silica gel 19 or bentonite. 20 Microwave irradiation of 1a impregnated onto the solid support for five minutes yielded no products and most of the substrate 1a was recovered (entries 4-6).…”

Thiirane functional spherosilicate as epoxy resin modifier

“…The cured samples were subjected to TG analysis. 1 H NMR (300 MHz), 13 C NMR (75 MHz), and 29 Si MNR (59 MHz) spectra were recorded on a Varian XL 300 spectrometer at room temperature using CDCl 3 as solvent. FT-IR spectra were recorded on a Bruker Tensor 27 Fourier Transform spectrometer equipped with a SPECAC Golden Gate diamond ATR unit.…”

“…Several methods of thiirane synthesis have been proposed in the literature, the majority of them are based on conversion of oxiranes to thiiranes [22,[25][26][27][28][29].…”

Synthesis of α-oxycarbanilinophosphonates and their anticholinesterase activities: the most potent derivative is bound to the peripheral site of acetylcholinesterase

“…Syntheses that normally require lengthy periods can be achieved conveniently and very rapidly in a microwave oven. As part of our efforts to explore the microwave-assisted methodology for the synthesis of organic compounds [26][27][28] , hereby we report a new method for the synthesis of α-oxycarbanilinophosphonates from the reaction of 1-hydroxyphosphonate with isocyanate under microwave irradiation, producing good to high yields of α-oxycarbanilinophosphonates.…”
