The Preparation of 2‐Arylmethylidene‐8‐methyl‐8‐azabicyclo[3.2.1]octan‐3‐ones
摘要:
An efficient and versatile two-step synthesis of 2-arylmethylidene-8-methyl-8-azabicyclo[3.2.1]octane-3-ones, via mono aldol condensation of tropinone with a variety of aryl aldehydes followed by pTsOH-catalyzed dehydration, is described.
