Regioselective total synthesis of (±) Neorautane, (±) Neorautanin and their analogs. Microwave mediated synthesis of 2H-chromenes from propargyl phenyl ethers

Add time:09/08/2019    Source:sciencedirect.com

Herein we describe the total synthesis of (±) Neorautane 1, (±) Neorautanin 2 and their analogs 15–18. The key intermediates Chromenes 10–13 were synthesised by microwave irradiation of propargyl phenyl ethers 8 and 9 in DMF under pressure.
