Convenient one-pot access to 2H-3-nitro-thiochromenes from 2-bromobenzaldehydes, sodium sulfide and β-nitrostyrenes

Abstract

An efficient synthesis of 2H-3-nitro-thiochromenes via cascade reaction was established. Starting from commercial available o-bromobenzaldehydes and -nitrostyrenes with sodium sulfide nonahydrate as an inexpensive sulfur source, various substituted thiochromenes were synthesized with high functional group tolerance without any added transition metal catalyst or additive.
