**Identification of short side chain sterols in the sponge __Damiriana hawaiiana__** The steroidal composition of the sponge __Damiriana hawaiiana__ is examined. Twenty‐seven components are identified. In addition to the C~26~‐C~29~, Δ^5^‐mono and diunsaturated sterols, the sponge contains sterols
Thirty‐two sterols are identified in the sponge __Hyrtios sp__. In addition to fourteen monohydroxylated compounds, the sterol fraction contains eight functionalized sidechain sterols, three of them new: 3 β‐hydroxy‐24‐norchol‐5‐en‐23‐al **(19)**, (22‐__trans__)‐3 β‐hydroxycholest‐5, 22‐dien‐24‐one
## Abstract Isotopically substituted styrene, (__phenyl‐^2^__H~5~) styrene (**3**), and selectively labled styrene, [alpha;, beta;‐^2^H~2~] styrene (**6**), were prepared by the classical two step synthesis, starting with the correspondingly labeled compounds. By anionic polymerization in an inert
