Reactions with 2-methyl- and 2-styryl-4-thiochromones

Diazoalkanes react with 2‐methyl‐ and 2‐styryl‐4‐thiochromones to yield the 1,3‐dithiolanes 1 and/or ethylenes 2–4. The latter are cleaved with thionyl chloride to give the corresponding ketones, while on fusion with sulfur they afford the corresponding thioketones. By condensation with compounds co...
