Correction to "Oxidative Substitution of Boranephosphonate Diesters as a Route to Post-synthetically Modified DNA".

Page 3259. In Scheme 2, compound 44, shown in brackets, should be renamed compound 45a, as shown here. In the text, the last sentence of the first paragraph of the section titled Mechanism of Iodine-Activated Substitution of Boranephosphonate Diesters should now read “(45a, Scheme 2)”, not “(44, Scheme 2)”. Page 3260. In the first sentence of the paragraph beginning “Thus, we conjecture...”, again “(44, Scheme 2)” should be replaced with “(45a, Scheme 2).” Further on in the same paragraph, in the discussion of NOESY spectra, compound numbers should be changed so that the text reads as follows: “...from each isomer (71 and 72, respectively). 9 showed much weaker NOE peaks between the BH3 hydrogens and the hydrogens on the ribose moiety when compared to 10. Similarly 71 (the product from 9) also showed weaker NOE signals between the methyl hydrogens and the sugar hydrogens than 72. These results support the conclusion that the BH3 group of 9 and the OCH3 group of 71 are in the same relative orientation at phosphorus.” Page 3261. In the Discussion section, near the end of the paragraph beginning “The high stability...”, “(such as 44)” should be replaced with “(such as 45a).” Supporting Information, pages S29 and S41. Compounds 47 and 48 should be renumbered as 71 and 72, respectively. The corrected Supporting Information is available here.
