  O-selective phosphorylation of nucleosides without N-protection

  摘要：

  A facile chemoselective O-phosphorylation of N-unprotected nucleosides has been achieved via metal alkoxide formation. Sequential treatment of N-unprotected nucleosides with an equimolar amount of a metallo-organic base such as an alkyllithium, potassium tert-butoxide, tert-butylmagnesium chloride, LiAl[N(CH3)2]4, Al[N(CH3)2]3, (i-C4H9)2AlH, etc., and a phosphorochloridate or p-nitrophenyl phosphate results in rapid O-phosphorylation to give the corresponding nucleotides in high yield. The method using magnesium alkoxides is among the best, considering its chemoselectivity, generality, and operational simplicity. The origin of the observed chemoselectivity is discussed.
