We have accomplished a new stereoselective synthesis of precoccinelline 1 in six steps from the chiral synthon 6 with a overall yield of 31 %. The main feature of this synthesis is the asymmetric synthesis of the trans 2,6-keto-acetal piperidine 14 which assures a stereospecific cyclisation in the construction of key intermediate ketone 4.
