Page 6-7, (2008/06/13)
Provided are methods of producing phosphitylated compounds, including 3′-O-phosphoramidites, comprising the step of reacting a hydroxyl-containing compound with a phosphitylating agent in the presence of a phosphitylation activator selected from the group consisting of: (1) acid-base complexes derived from an amine base of Formula I 1wherein R, R1, and R2 are independently C1-C10 alkyl, C1-C10 cycloalkyl, C1-C10 aryl, C1-C10 aralkyl, C1-C10 heteroalkyl, or C1-C10 heteroaryl; (2) acid-base complexes derived from an amine base of Formula II 2wherein R3, R4, R5, R6, and R7 are independently hydrogen, C1-C10 alkyl, C1-C10 cycloalkyl, C1-C10 aryl, C1-C10 aralkyl, C1-C10 heteroalkyl, or C1-C10 heteroaryl, and at least one of R3, R4, R5 R6, and R7 is not hydrogen.; (3) acid-base complexes derived from a diazabicyclo amine base; (4) zwitterionic amine complexes; and (5) combinations of two or more thereof, to produce a phosphitylated compound.
