Herein, we demonstrated a silver/K2S2O8-mediated highly regio- and diastereoselective 6/5-exo trig radical cascade cyclization of alkyne-tethered cyclohexadienones with sulfonyl hydrazides or sodium sulfinates subsequent selenation to access 6,6-dihydrochromenone 6,5-fused tetrahydro benzofuranone derivatives. This reaction protocol features high functional group compatibility has wide substrate scope providing variety dihydrochromenones derivatives in good excellent yields. The proceeds via the attack alkyne over activated Michael acceptor. TEMPO quenching experiment implies presence intermediate. Further synthetic versatility 6,6- 5,6-fused is also showcased.

Abstract A variety of 2-substituted 3-selanyl-chromenones are readily prepared through a cascade selanylation/cyclization alkynyl aryl ketones with sulfonoselenoates. This transformation is performed under metal-free conditions and does not require an additional oxidant. It also has the advantage broad functional group tolerance scalability.
