Abstract: Four difenoconazole stereoisomers were well separated on a Superchiral S-OX column. The absolute configurations of the four stereoisomers of difenoconazole eluted in an orderly fashion with the chiral column were confirmed as (2S,4S), (2S,4R), (2R,4R),… read more here.

Abstract: Abstract Germicidin N (3-ethyl-4-hydroxy-6-[(1S, 2 R)−2-hydroxy-1-methylpropyl]-2H-pyran-2-one, 1), a new α-pyrone from the extracts of a Streptomyces sp. derived from marine algae, has been synthesized for the first time as four possible diastereomers from chiral β-hydroxyester ((S)−6… read more here.
