Abstract
The potential of (S,S)-3,5-bis(α-trimethylsilyloxyethyl)-1,2,4-triazole
3 and (S,S)-3,5-bis(α-methoxyethyl)-1,2,4-triazole
9 as chiral synthetic intermediates has been investigated. Reaction of the chiral triazole
3 with ethyl 2-bromopropionate and subsequent treatment with LDA followed by quenching with an electrophile gave either esters
5 or lactones
6&7 in good yields with generally excellent diastereoselectivities.
