Cyclopropanation with iron(III) phthalocyanine

Posted by naturalproductman on May 2, 2015

Emily Balskus and colleague have reported in ACIE on an iron(III) phthalocyanine catalyst that can perform cyclopropanation reactions. Reminds me of the P450 version that was published a few years back.

Vegfrecine

Posted by naturalproductman on February 22, 2013

Hayamitsu Adachi and co-workers from BIKAKEN have reported in JNP on a novel VEGF receptor tyrosine kinase inhibitor from bacteria. The only problem I see with this compound – from a toxicologist’s perspective – is that this is a quinone, and thus a very reactive electrophile. If this kind of functional group is used as a drug, who knows what other things it will react with in the body – be it DNA, proteins, etc…
