Phyllanthurinolactone ( 1 ) and its three stereoisomers 18 − 20 were synthesized, and only 1 was bioactive as the leaf‐closing factor of a nyctinastic plant, Phyllanthus urinaria L. X‐ray analysis of the tetraacetylglucoside 17 was executed, and the absolute configuration of 1 was determined as 6 S, 7a R .
