Three new coumarins, seselinal, sesibiricol and sibirinol, and 12 known coumarins have been isolated from the umbels of seseli sibiricum.The new coumarins have been characterized as 5,7-dimethoxy-8-(2-methyl-2-formylpropyl)-2H-1-benzopyran-2-one, 5-(3-methylbut-2-enyloxy)-7-methoxy-8-(2-hydroxy-3-methylbut-3-enyl)-2H-1-benzopyran-2-one and 5,7-dimethoxy-8-(2-hydroxy-3-methylbut-3-enyl)-2H-1-benzopyran-2-one, respectively.The known ones were identified as sesibiricin, isosibiricin, osthol, coumurrayin, sesebrin, sesebrinol, sibiricin, imperatorin, bergapten, xanthotoxin, isopimpinellin and mexoticin.Key Word Index - Seseli sibiricum; Umbelliferae; umbels; coumarins; 2H-1-benzopyran-2-one; seselinal; sesibiricol; sibirinol; isosibiricin; sesibiricin; osthol; coumurrayin; sesebrin; sesebrinol; sibiricin; imperatorin; bergapten; xanthotoxin; isopimpinellin; mexoticin.

A synthetic approach to confirm the structures of toddanol (1) and toddanone (2) has been provided.In addition, coumurrayin (12), sibiricin (13), isosiribicin (14), toddaculin (8) and aculeatin (9) have also been synthesised.
