Syntheses of all stereoisomers of aptosimon (9-oxosesamin) and their effects on plant growth regulation and diacylglycerol acyltransferase inhibition
{{output}}
All eight stereoisomers of aptosimon (9-oxosesamin) were synthesized by employing Evans' anti- and syn-aldol condensations. Among them, the (7S,7'R,8R,8'S)-aptosimon was more active than (+)- and (-)-sesamin at 1×10-5 M in promoting lettuce root growth und... ...
