Replacement of the double bond of antitubulin chalcones with triazoles and tetrazoles: Synthesis and biological evaluation.

Bioorg. Med. Chem. Lett. 21(2) , 764-8, (2011)

In the chalcone scaffold, it is thought that the double bond is an important structural linker but it is likely not essential for the interaction with tubulin. Yet, it may be a potential site of metab...

Total synthesis of ecteinascidin 743.

J. Am. Chem. Soc. 128(1) , 87-9, (2006)

A convergent total synthesis of ecteinascidin 743 is realized from five building blocks of almost equal size. It takes 23 steps from l-3-hydroxy-4-methoxy-5-methyl phenylalanol (5) with an overall yie...
