Abstract
The novel N-phenyl-2-furohydrazonyl chloride4A and its p-nitro analog4B have been prepared and identified. The cycloaddition reactions of nitrilimines5A and5B, derived by base catalyzed dehydrochlorination of4A and4B respectively, to a variety of dipolarophiles were investigated. The results showed that4A and4B are useful precursors for synthesis of differently substituted 3-(2-furyl)-2-pyrazoline derivatives and their pyrazoles and analogs.
