Acyl and sulfonyl hydrasides react with ortho esters to form hydrazirmdocarboxylate 2 ester derlvatlves (RCOERXV=CROR and RSO$HN=CROR, respectively). It has now been found that oi-methoxyalkylldenetrlphenylphosphazlnlum brormdes (2) are obtained efficiently by reactlon of trlmethyl ortho esters (2)
N.m.r. spectroscopy has proved extremely fruitful for studying the configuration and conformation of many carbohydrates and their derivatives. The reactions of boric acid with dials in solution have been used for almost a centur! lo examine structural differences among carbohydrates. However. studie
