Abstract
The first syntheses of bioactive cryptophycins functionalized at unit ID were accomplished ina one-pot Staudinger reduction/cyclization step An a/ado precursor for the lower part of the backbone was introduced to minimize protective group chemistry and enable a very convenient synthesis of cryptophycin-52 and unit D eryptophycin analogues containing an ester or a free carboxylic acid for bioconjugations Both new cryptophycin derivatives show high biological activity in cytotoxicity assays
