Abstract

Preparations of C10 acetate, trifluoroacetate, and chloro derivatives of dicyanocobyrinic acid heptamethyl ester ('cobester') are described. The nature and properties of intermediates in the synthesis of the 10-chloro derivative are discussed, and the electronic absorption spectra of the products are presented.
