摘要
The structure of piplartine (=piperlongumine) was established as (E)-N-3'',4'',5''-trimethoxycinnamoyl-5,6-dihydro-2(1H)-pyridone (13) by synthesis and by an X-ray crystallographic analysis. Model condensation of (E)-3,4,5-trimethoxycinnamoyl chloride and crotonamide gave not the expected cinnamoylcrotonamide, but (E)-N-3'',4'',5''-trimethoxycinnamoyl-3-chlorobutyramide (12).
