Trichodermin (12,13-ep-oxy-trichethec-9-en-4?-yl 4-fluoro-benzoate).


ABSTRACT: IN THE TITLE TRICHODERMIN COMPOUND (SYSTEMATIC NAME: 12,13-ep-oxy-trichothec-9-en-4?-yl 4-fluoro-benzoate), C(22)H(25)FO(4), the five-membered ring displays an envelope conformation, whereas the two six-membered rings show the different conformations, viz. chair and half-chair. As for the seven-membered ring, the dihedral angle between the mean planes formed by the four C atoms of the envelope unit and the three C and one O atoms of the six-membered chair is 68.67?(2)°; these two mean planes are nearly perpendicular to the ep-oxy ring with angles of 87.97?(2)and 88.14?(2)°, respectively.
