Title	Synthesis of Facial Amphiphile 3,7-Diamino-5α-cholestane Derivatives as a Molecular Receptor
Author	Md Wasi Ahmad, Young Mee Jung, Sharaf Nawaz Khan, Hong Seok Kim*
Keywords	Facial amphiphile, Anion receptor, Reductive amination, Aminosteroids, Stereoselectivity
Abstract	A series of facial amphiphiles 3,7-diaminocholestane were synthesized from 3,7-diketocholestane via 2 sequential reductive aminations and anion recognition was evaluated with acetate, chloride, bromide, fluoride and phosphate anions. The stereo-selective reductive amination protocol was utilized to synthesized facial amphiphiles afforded receptors in high yields. The molecular receptor 2 showed the highest binding constant with acetate in a 1:1 ratio.
