Determination of Absolute Structure of Macroviracins by Chemical Synthesis
摘要:
The relative and absolute configurations of macroviracins have been established by the stereocontrolled synthesis of methyl ester 2a of the C-22 carboxylic acid, a constitutive fatty acid of macroviracin A (1), and their comparison to a sample 2 derived from the natural product 1.
