-
Paragraph 0044; 0045, (2017/09/19)
The present invention discloses a preparation method for (+)-danshensu and an analogue thereof, wherein a metal arylation reagent directly and asymmetrically reacts with 2(R),3-epoxypropionic acid and an analogue thereof to obtain (+)-danshensu maintainingchirality and the analogue thereof. Compared to the existing method, the method of the present invention has advantages of simplicity, effectiveness, high raw material economy, high yield, significantly reduced compound production cost, and great industrial value.

supporting information, p. 5047 - 5050 (2016/07/25)
An asymmetric synthesis of (+)-salvianolic acid A with cardioprotective properties, has been accomplished in a convergent manner in eight steps and 10.6% overall yield. This synthesis features an asymmetric addition of organometallics to optically pure 2,3-epoxypropionate in the presence of BF3·Et2O, Ru(III)-catalyzed directed [Formula presented] olefination, and I2-catalyzed isomerization reaction.

, p. 981 - 982 (2007/10/03)
The first total synthesis of a molecule possessing the structure proposed for keramamide J is described, providing data indicating that the structure of this natural product should be re-examined.
EFFICIENT SYNTHESES OF ENANTIOMERICALLY PURE L AND D-ALLOTHREONINES AND (S) AND (R) ISOSERINES

, p. 5023 - 5026 (2007/10/02)
Both enantiomers of (S) 1 and (R) 2 isoserine as well (D) 3 and (L) 4 allothreonine are prepared optically pure in three steps by asymmetric Sharpless epoxidation of crotyl and allylic alcohols into 7-10 followed by an improved RuCl3/NaIO4/water oxidation procedure to low molecular weight glycidic acids 11-14 and epoxide opening by ammonia with (20-33 percent) overall yields.
