摘要：

The structure of porritoxin, a phytotoxin. of Alternaria porri, was reinvestigated by detailed 2D NMR analysis including H-1-C-13 and H-1-N-13 HMBC experiments The structure of porritoxin was determined to be 2 (2' hydroxyethyl) 4 methoxy 5 methyl 6 (3" methyl 2" butenyloxy)-2,3-dihydro 1H isomdol 1 one (1) Thus our previous proposed structure, 8-(3',3'-dimethylallyloxy)-10 methoxy 9 methyl 1H- 3 4 dihydio-2,5 benzoxazocin 6(5H) one (2), is incorrect.
