- New synthetic method of natural product moracin Y
-
The present invention relates to a first and novel synthetic method of a moracin Y which is contained in mulberry leaves in an infinitesimal amount and exhibits an anticancer activity. The present invention includes a development of a novel synthetic method for efficiently synthesizing the moracin Y through three reaction stages which are a regioselective iodination, a sonogashira coupling, and a desilylation, starting from a 2,4-dihydroxybenzaldehyde which is a cheap compound.COPYRIGHT KIPO 2015

- Asymmetric total synthesis of smyrindiol employing an organocatalytic aldol key step
-
The first organocatalytic asymmetric synthesis of smyrindiol, by using an (S)-proline catalyzed enantioselective intramolecular aldol reaction as the key step, is described. Smyrindiol was synthesized from commercially available 2,4-dihydroxybenzaldehyde in 15 steps, with excellent stereoselectivity (de = 99%, ee = 99%). In the course of this total synthesis a new and mild coumarin assembly was developed.

- The first total synthesis of moracin O and moracin P, and establishment of the absolute configuration of moracin O
-
The first total synthesis of the naturally occurring benzofurans, moracins O and P was achieved using a Sonogashira cross coupling reaction followed by in situ cyclization, and the absolute configuration of natural moracin O was established.
