A rhodium-catalyzed synthesis of isoquinolino[1,2-b]quinazolines via C-H annulation using vinylene carbonate as an oxidizing acetylene surrogate in biomass-derived γ-valerolactone (GVL) was developed. The reactions proceeded smoothly to give the corresponding products in moderate to good yields without any external oxidant and base. This protocol was applied for the synthesis of 5,6-dihydro-8H-isoquinolino[1,2-b]quinazolin-8-ones. In the part of experimental materials, we found many familiar compounds, such as Vinylene carbonate(cas: 872-36-6Synthetic Route of C3H2O3)
Vinylene carbonate(cas: 872-36-6) belongs to esters. Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.Synthetic Route of C3H2O3
