- •
A novel synthesis of poly substituted chromenes has been developed.
- •
The procedure is applicable for various salicylaldehydes and alkynylsilanes.
- •
Alkynes not having electron withdrawing substituents was used.
- •
The present reaction provides a versatile access to functionalized 2H-chromenes.
