Title: | Stereocontrolled synthesis of linear 22R-homoallylic sterols via a triflic acid-catalyzed 2-oxonia cope rearrangement | Authors: | Loh, T.-P. Hu, Q.-Y. Ma, L.-T. |
Issue Date: | 11-Jul-2002 | Citation: | Loh, T.-P., Hu, Q.-Y., Ma, L.-T. (2002-07-11). Stereocontrolled synthesis of linear 22R-homoallylic sterols via a triflic acid-catalyzed 2-oxonia cope rearrangement. Organic Letters 4 (14) : 2389-2391. ScholarBank@NUS Repository. https://doi.org/10.1021/ol026136e | Abstract: | (Matrix presented) Poor stereoselectivity caused by the involvement of side reaction pathways was observed in the In(OTf)3-catalyzed allyl-transfer reaction (R = electron-withdrawing group). Subsequently, it was found that the employment of triflic acid (TFA) as catalyst could successfully suppress the side reaction pathways and, hence, achieve high stereoselectivity. | Source Title: | Organic Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/94878 | ISSN: | 15237060 | DOI: | 10.1021/ol026136e |
