The crystal and molecular structure of a dioxan photoadduct of 3‐dehydro‐gibberellin A1 methyl ester

Abstract

AbstractThe three‐dimensional structure of a dioxan photoadduct of 3‐dehydro‐gibberellin A1 methyl ester has been established as (2′S)‐3‐[dioxanyl‐(2′)]‐3‐epi‐gibberellin A1 methyl ester (1) by X‐ray analysis. The compound crystallizes in the orthorhombic space group P212121 with four molecules in the unit cell of dimensions a = 9.751, b = 22.189, c = = 10.064 Å. The final R‐value is 0.103 for 1151 reflections.
