Young-Ger Suh,Jae-Kyung Jung,Seung-Yong Seo,Kyung-Hoon Min,Dong-Yun Shin,Yong-Sil Lee,Seok-Ho Kim,Hyun-Ju Park +7 more
TL;DR: The key parts of this approach include the stereoselective construction of the cis-disubstituted hydroxycyclopentane skeleton and the direct introduction of the C1-C3 acrylate moiety using a new variant of a trans-vinylogous acyl anion equivalent.
Journal ArticleDOI
Highly efficient deacetylation by use of the neutral organotin catalyst [tBu2SnOH(Cl)]2.
TL;DR: The mildness of the reaction gives rise to great synthetic versatility and in the process a variety of functional groups are tolerated and the crude product thus obtained can be used for further reactions without purification.
Journal ArticleDOI
Sn(IV)-based organometallics as catalysts for the production of fatty acid alkyl esters
TL;DR: In this paper, the mechanistic aspects and applications of organotin(IV) catalysts are discussed and the potential application of this type of catalyst in the synthesis of fatty acid alkyl esters (FAAEs) is also presented.
