Chemoselective deprotection of tertiary benzylamines and reduction of carbon–carbon double bonds in the presence of benzyl and benzyloxymethyl ethers
摘要:
Catalytic transfer hydrogenation using 10% Pd-C in the presence of 1,4-cyclohexadiene as the hydrogen donor selectively debenzylates amines and reduces carbon-carbon double bonds while leaving benzyl and benzyloxymethyl ethers intact. (C) 2000 Elsevier Science Ltd. All rights reserved.

beta]-amino fluoride substitution mediated by La[N(SiMe3)2]3 has been developed. The reaction proceeds via a reactive aziridiniumionintermediate, which readily reacts with various nucleophiles. This allows the use of fluorine as a modular functionality and further expands the role of aziridiniumions in organic synthesis.
