S-seco-porphyrazine as a new member of the seco-porphyrazine family – Synthesis, characterization and photocytotoxicity against cancer cells

Total synthesis of seco-lateriflorone

A convergent strategy toward the synthesis of lateriflorone (5) is described. Our approach is based on biosynthetic considerations and draws on a sequence of prenylation, oxygenation and Claisen reactions for the construction of chromenequinone 6, and a tandem Claisen/Diels–Alder reaction cascade for the synthesis of caged tricycle 7. Union of fragments 6 and 7 led to the synthesis of secolater...

Synthesis of the B-seco limonoid scaffold.

The underlying stereochemically complex and densely functionalized scaffold of the B-seco limonoids was synthesized employing an Ireland-Claisen rearrangement as key transformation.
