A new process for preparing a compound of Formula V, wherein P is a hydroxy protecting group and R is acetyl, said process including the steps of: i) selectively deacetylating the 10-hydroxy group of 9-dihydro-13-acetylbaccatin III with N,N-dimethylethylenediamine to produce 9-dihydro-10-deacetyl-13-acetyl-baccatin III; ii) concomitantly protecting 7-hydroxy and 10-hydroxy groups of the reaction product of step i); and iii) oxidizing the 9-hydroxy group of the reaction product of step ii) with an oxidizing agent to produce the compound of formula V.
182 Process for preparing optically active antrocin US13618016 2012-09-14 US08658806B2 2014-02-25 Dar-Fu Tai; Venkatachalam Angamuthu; Yew-Min Tzeng
The present invention relates to a process of preparation of optically active antrocin. At first, to introduce the correct configuration of trans-decalone, alkyl aluminum/TMSCN was used to react with decalenone. The resulting racemic nitrile-decalone was resolved with chiral diol by ketalization to produce two chromatography separable diasteromers. After a simple column chromatography, optically pure compounds were obtained. Formylation was a critical step for the lactone formation. The rest of the synthesis is straight forward through oxidation and olefination. Accordingly, the total synthesis was completed in 10 steps with 7% overall yield from commercially available 6-methoxy-2-tetralone.
