Abstract

Oligomeric Isoflavonoids. Part 3. Daljanelins A-D, the First Pterocarpan-and Isoflavonoid-Neoflavonoid Analogues. -The title daljanelins are isolated from Dalbergia nitidula. The structure and stereochemistry of daljanelin C (VIII) are unambiguously confirmed by an independent synthesis starting from the pterocarpan derivative (I). -(FERREIRA, J. A.; NEL, J.
