WebAn example of a one-pot synthesis is the total synthesis of tropinone or the Gassman indole synthesis.. A sequential one-pot synthesis with reagents added to a reactor one at a time and without work-up is also called a telescoping synthesis.. In one such procedure the reaction of 3-N-tosylaminophenol I with acrolein II affords a hydroxyl substituted … WebThe Gassman indole synthesis involves a one-pot process in which a hypohalite, a α-carbonyl sulfide derivative, and a base are added sequentially to aniline or substituted aniline to provide 3-thioalkoxy indole [25]. Mori-Ban reaction involves intramolecular Heck reaction of o-halo-aniline with pendant olefin to prepare indole [26].
