| Abstract: | Three new phragmalin‐type limonoid orthoesters, velutabularins K–M ( 1 – 3 ) and seven structurally related known compounds were isolated from the bark of Chukrasia tabularis var. velutina. The structures of these compounds were elucidated by spectroscopic analysis. The structure of 1 was confirmed by single crystal X‐ray diffraction. In addition, the brine shrimp lethality of compounds 1, 3 , and the known compounds was evaluated. |
