Remarkable solvent effect in Barton–Zard pyrrole synthesis: application in an efficient one-step synthesis of pyrrole derivatives
摘要:
A unique solvent effect encountered in the Barton-Zard pyrrole synthesis was exploited to develop an efficient synthesis of pyrrole-2-esters. The chemistry was extended to a one-pot synthesis of pyrrole-2,4-dicarboxylates. (c) 2006 Elsevier Ltd. All rights reserved.

β-Nitroalkanols are easily obtained within a few minutes, through the nitroaldol (Henry) reaction, catalyzed by a stoichiometric amount of powdered potassium hydroxide, in dry media. Satisfactory to excellent yields are obtained both with primary and secondary nitrocompounds, either with aromatic or aliphatic aldehydes.

A process of producing organic compounds, such as acetaminophen, nitroalcohols and indoles, employs a catalyst system of an oxyethylene ether and a metal containing inorganic or organic reagent. The oxyethylene ether at least partially complexes the metal of the inorganic or organic reagent. As such, the reactions may be conducted neat. The processes are environmentally friendly and operationally simple.
