Low-valent titanium mediated reductive cleavage of O/N-trityl bonds via free radical pathway

Rele, Shyam,Nayak, Sandip K.

, p. 3533 - 3540 (2002)

Low-valent titanium mediated cleavage of trityl-O/N bonds in trityl ethers/amines via electron transfer process is reported. Chemoselective deprotection of trityl ethers in preference to benzyl ethers is achieved. The ease of cleavage of protected alcohols and amines is in the order O-allyl > O-trityl > O-benzyl; N-trityl > O-trityl bonds.
