Stitching ynones with indolin-2-thiones: an eco-friendly reaction cascade towards functionalized thiopyrano[2,3-<i>b</i>]indoles and their inceptive optoelectronic profiling
A sustainable approach embodying many green features and leading to a tricyclic thiopyrano[2,3-<i>b</i>]indole system through the base-mediated stitching together of ynones with indolin-2-thiones <i>via</i> a tandem Knoevenagel condensation, 6π-electrocyclization, and 1,5-H-shift reaction cascade has been observed and generalised. Initial optoelectronic profiling of these new entities reveals their potential as blue light emitters for organic light-emitting diodes (OLEDs).
