The epimeric mixture of the trans-substituted tetrahydropyran derivatives (1) was transformed to the cis-substituted lactone (6), which was converted into the piperidine (3), the synthetic intermediate of dihydrocinchonine (5a) and dihydrocinchonidine (5b), and the synthetic precursor (11) of (+/-)-dihydroantirhine (4).
