Paragraph: Phenanthroquinolizidine alkaloids a b s t r a c t The stereoselective synthesis of epi-thieno analogues of the phenanthroquinolizidine bioactive alkaloids (À)-Cryptopleurine and (À)-(15R)-Hydroxycryptopleurine was achieved in five steps starting from easily available enantiopure (S)-2-aminoadipic acid used as chiral pool and nitrogen atom source. During these investigations, both p-cationic cyclization of chiral N-thienylmethyl-6-oxopipecolinic acids into pure (S)keto-lactams and theirs regioselective and diastereoselective reduction, considered as key steps of this sequence, were studied. Of particular interest, the FriedeleCrafts cyclization using (CF 3 CO) 2 O/BF 3 $Et 2 O show that near the expected keto-lactams, enamides and enamidones containing trifluoromethyl residue were isolated. A mechanism leading to the latter products with high synthetic potential was discussed.
