The synthesis of 1,2,6-trisubstituted indoles from accessible 6-propargylcyclohex-2-enones and primaryamines is reported. Simple acidcatalyzed amination–cyclization reaction followed by air oxidation of the corresponding intermediated 4,5-dihydroindoles was found to be suitable to obtain the desired indoles. The reaction tolerates a variety of functional groups on the starting cyclohex-2-enones and

Abstract Bicyclo[3.3.1]nonane system is an important structural motif in many natural compounds. This article describes a short syntheticroute to the bicyclo[3.3.1]nonane system via aldol condensation. The proposed strategy is based on the use of cyclohex-2-en-1-ones containing an additional carbonyl group in the side chain as a key precursor. The approach showed good results for compounds with electron-donating
