Reactions of Relevance to the Chemistry of Aminoglycoside Antibiotics. Part 13. A Novel Synthesis of Benzyl Ethers

Barrett, Anthony G. M.,Read, Roger W.,Barton, Derek H. R.

, p. 2184 - 2190 (2007/10/02)

Benzyl ethers were prepared from alcohols by reaction with chloro(phenylmethyl)dimethylammonium chloride and sodium hydrogen telluride in sequence.The salt (1) 1)OR2Cl-; R1=H, R2=cholest-5-en-3β-yl> and sodium borohydride gave the borane complex of 3β-dimethylaminomethoxycholest-5-ene.Salt (1; R1=Ph, R2=cholest-5-en-3β-yl or 5α-cholestan-3β-yl) and ammonia or hydrazine gave the steroidal benzimidates or benzhydrazonate.
