An Efficient Synthesis of Dihydrobenzo[c]azepines from Morita–Baylis–Hillman Adducts via Pictet–Spengler Reaction

Abstract

Various dihydrobenzo[c]azepines were synthesized in good yields via Pictet-Spengler cyclization protocol from tosylamide derivatives of Morita-Baylis-Hillman adducts and 1,3,5-trioxane. The synthesis was carried out in the presence of easily removable montmorillonite K-10 in short time in high yields.

Carbon Aerogels Synthesizd with Cetyltrimethyl Ammonium Bromide (CTAB) as a Catalyst and its Application for CO2 Capture

“…Porous carbons such as carbon aerogels have received much attention for their extensive applicability as CO 2 adsorbents due to their special pore structure, variable surface properties, high thermal stability and low cost , . The carbon aerogels synthesized by precursors of resorcinol and formaldehyde was widely studied . In the preparation process of the carbon aerogels, the catalyst used is an important factor for structure and properties of carbon aerogels.…”
