A number of hexadeuterated brassinosteroids (BS) containing a hydroxy group at C-22 or a 22R,23R-diol function were prepared starting from 23,24-bisnorcholenic acid methyl ester for biosynthetic studies. Synthesis of the cyclic part was accomplished via the initial hydroboration–oxidation of Δ 5 -double bond. The key step in the synthesis of the side chain involved addition of (2S)-[3,4- ...
Two hexadeuterated brassinosteroids (BS) ([26,27-2H6]-23-dehydroxycastasterone and [26,27-2H6]-cathasterone) containing a hydroxy group at C 22 instead of the 22R,23R-diol function characteristic for most compounds of this class were prepared for biochemical studies. The corresponding non-deuterated compounds are considered intermediates in brassinolide biosynthesis. The carbon skeleton of...
A number of [26- 2 H 3 ]brassinosteroids were prepared for biochemical studies. The parent, nondeuterated compounds were considered to be biosynthetic intermediates in brassinosteroid biosynthesis. Claisen rearrangement was used to construct the steroidal side chain. Deuterium was introduced by reducing the corresponding intermediates with lithium aluminium deuteride.
