The molecular and crystal structures of gibberellin a 4 and gibberellin a 13 methyl esters

, : The molecular and crystal structures of gibberellin a 4 and gibberellin a 13 methyl esters. Journal of the Chemical Society Perkin Transactions I (7): 1922-1926

The X-ray structures of gibberellin A4 methyl ester and gibberellin A13 trimethyl ester [plant hormones] were determined. Ring A is flattened and the crowding of C(7) by C(18) and C(15) is greater in gibberellin A13 trimethyl ester than gibberellin A4.
