A Lilly group21"3 devised a synthesis of the bacterial cell wall precursor UDP-N-acetylmuramyl-pentapeptide (Park nucleotide) in which deprotection of a 2-(phenylsulfonyl)ethyl ester using a catalytic amount of DBU in dichloro-methane220,221 was an important step in the release of a carboxyl group [Scheme 6,99]. 2-(Methylsulfonyl)ethyl esters have also been cleaved under basic conditions to release a protected carboxylic acid. Scheme 6.100 shows an example from the closing stages of a synthesis of Surugatoxin.222...
