## Abstract Synthesis of labeled brassinosteroids (24‐epibrassinolide and its biosynthetic precursors) containing three deuterium atoms in the terminal part of the side chain is reported. Labeling was achieved by three‐step reductive transformation of carbethoxy group into methyl using lithium alum
The endoperoxide II has been shown to be a key intermediate m the synthesis of primary (E and F) prostaglandins from C20 unsaturated fatty acids such as all cis-eicosa-8,11,14-trienoic acid.
Pantoneurotriols la and 2a are acyclic polyoxygenated monoterpenes isolated from tile Antarctic en~mism Pantoneura plocamioides together with compounds 3 and 4. Tile stereochemistries of these compounds were established by spectroscopic methods and pantoneurotriols have been proposed as biogenetic p
