Although TEMPO-catalyzed oxidation of 7 proceeded cleanly, separation of TEMPO from the product 8 was difficult. Use of 4-acetamido-TEMPO circumvented this purification problem. For TEMPO-catalyzed oxidation employing NCS as the oxidant, see:

In the previous report, we recommended the addition of tributylstannous methoxide as a catalyst to effect the in situ trapping of isocyanates with alcohols. Dibutyltin maleate offers advantages of low cost and ease of purification steps to remove residual organotin byproducts. See:

Our initial route to 16 involved oxidative cleavage of the alkene moiety in 13 with sodium periodate and a catalytic amount of osmium tetroxide in the presence of 2,6-lutidine (. ). In this case, the subsequent reduction of the resultant products with sodium borohydride in methanol occurred smoothly to afford the diol i in 60% yield over two steps.{A figure is presented}
