Catalyst-Free One-Pot Access to Pyrazoles and Disulfide-Tethered Pyrazoles via Deamidative Heteroannulation of β-Ketodithioesters with Semicarbazide Hydrochloride in Water
operationally simple, mild, and catalyst‐free one‐pot protocol to access privileged pyrazoles and disulfide‐tethered pyrazoles has been devised by [3+2] heteroannulation of β‐ketodithioesters with semicarbazide hydrochloride in water under open air. The pH of the medium played a key role toward the selectivity switch, as refluxing in water led to the formation of pyrazoles, whereas addition of sodium acetate
