Abstract: All four stereoisomers of naturally occurring 6-(2-hydroxy-6-phenylhex-1-yl)-5,6-dihydro-2H-pyran-2-one (1) were synthesized by employing yeast-reduction products with high optical purity (95%ee-more than 99% ee), and then their phytotoxicities against lettuce and Italian ryegrass were evaluated. In the… read more here.
