(−)-Desoxoprosopinine was synthesised from (R)-phenylglycinol as the chiral source. The three distinct steps used for the construction of the three stereogenic centers of the target were all highlydiastereoselective. These steps include a reduction of a homochiral N-Boc-2-acyl oxazolidine and the stereoselectivity of this reaction can be explained by a non chelated model. An original N-debenzylation
