Excited to share our latest work! We present a one-pot photochemical route to 4-chromanone-fused estrones via tandem photo-Fries rearrangement and oxa-Michael cyclization.
This continues our collaboration with Sergio Bonesi on steroid photochemistry.

Photochemical construction of chromanone‐fused estrones using a biphasic tandem rearrangement–cyclization approach
A photochemical one-pot two-step methodology has been developed for the facile preparation of 4-chromanone fused to estrone (and 17-norestrone) derivatives under base- and acid catalysis upon direct ...

🚨 New paper out!
We designed and synthesized a library of pseudo-natural products vía tandem Ugi chemistry.
One of them inhibits both Zika and SARS-CoV2, possibly by targeting host lipid droplets.
Check it out 👇
