N,N-Bis[trifluoroacetyl]-L-homocystine dimethyl ester (1) was condensed with adenosine (2a), 3-deazaadenosine (2b), and 7-deazaadenosine (2c) in the presence of tri-n-butylphosphine in pyridine or dimethylformamide to give the N-trifluoroacetyl-Sadenosyl-homocysteine derivatives 3a, 3b and 3c with aqueous barium hydroxide afforded S-adenosylhomocysteine (4a), S-3-deazaadenosylhomocysteine (4b), and S-7-deazaadenosylhomocysteine (4c) in good yields.
