Hemetsberger–Knittel and Ketcham Synthesis of Heteropentalenes with Two (1:1), Three (1:2)/(2:1) and Four (2:2) Heteroatoms

Hemetsberger–Knittel and Ketcham Synthesis of Heteropentalenes with Two (1:1), Three (1:2)/(2:1) and Four (2:2) Heteroatoms

The synthetic methods leading to furo[3,2-<i>b</i>]pyrroles and thiazolo [5,4-<i>d</i>]thiazoles are reviewed herein. Furo-, thieno- and seleno [3,2-<i>b</i>]pyrroles are related to heteropentalenes, containing two heteroatoms in the entire structure, one each per...
