Abstract
Cholest-5-en-3β-oxy-5-bromopentane (1) and cholest-5-en-3β-oxy-11-bromoundecane (2), key precursors for the synthesis of novel cationic amphiphiles based on cholesterol, have been synthesized and characterized by 1H-NMR spectroscopy and X-ray crystallography. Thermal disorder and effect of length of the bromoalkyl segment on the crystal structure have been investigated. Possible molecular level explanation of the unusual alternating s-trans-gauche conformation of the bromopentyl side chain of (1) has been presented.
