The isomeric mixture of ethyl 5,6-dihydro-4H-pyrrolo[1,2-b]pyrazole-2- and −3-carboxylates (14 and 15), derived from a proline meso-ionic synthon, demonstrated remarkably different stabilities towards alkaline hydrolysis. On that basis, a nonchroma

Alkylation of the 2-mercaptoacetamide 4a with chloropropanone afforded the ketoamide 10 which on direct acid-catalyzed cyclization furnished 12. The cyclization can be arrested at the stage of the enamide 11. Periodate oxidation of 12 gave the equato

The condensations of 1-(2-hydroxyphenyl) pyrroles with a variety of carbonyl compounds are shown to give new 4-substituted-4H-4-methylpyrrolo[2,1-c][1,4]benzoxazines. Some of the products were further functionalized. The ir, uv, and pmr spectra of th

The condensation of thiotryptophol with β-ketoesters and successive hydrolysis of the intermediates afforded the title compounds which represent a novel ring system. The reaction of thiotryptophol with ethyl propiolate in the presence of sodium meth

A series of novel 1,3,4,9-tetrahydro-1-methyl-thiopyrano-[3,4-b]indole-1-ethanamines has been synthesized and examined for effects on reserpine-induced ptosis and reserpine-induced hypothermia in mice. One member of the series, the 9-ethyl-N,N-dimeth
