2. Two Novel Polyhydroxysteroids with a 24-Ethyl-25-hydroxy-26-sulfoxy Side Chain from the Deep Water Starfish Styracaster caroli

Author

Riccardis, F. De, Izzo, I., Iorizzi, M., Palagiano, E., Minale, L., and Riccio, R.

Abstract

The structure of two minor polyhydroxysteroids isolated from the deep water starfish Styracaster caroli were determined as (22E,24R,25R)-24-ethyl-5α-cholest-22-en-3β,5,6β,8,15α,25,26-heptol 26-sulfate (1) and (24R,25R)-24-ethyl-5α-cholestane-3β,5,6β,15α,16β,25,26-heptol 26-sulfate (2). The stereochemistry at the C-24 and C-25 positions was determined by enantioselective synthesis of 2-methyl-3-ethylheptane-1,2-diols as models and by comparison of the 1H-NMR data of their (+)- and (−)-MTPA esters with those of the 26-MTPA esters of the 22,23-dihydro derivative of the naturally occurring 1 and of 2.
