Gram-scale carbasugar synthesis: Via intramolecular seleno -Michael/aldol reaction
Banachowicz, Piotr,Buda, Szymon
, p. 12928 - 12935 (2019)
Carbasugars represent an important category of natural products possessing a broad spectrum of biological activities. Lots of effort has been done to develop gram scale synthesis. We are presenting a new approach to gram scale synthesis of the carbasugar skeleton via intramolecular seleno-Michael/aldol reaction. The proposed strategy gave gram amounts of 6-hydroxy shikimic ester in a tandem process in 36% overall yield starting from d-lyxose. We have attempted to demonstrate the synthetic utility of 6-hydroxyshikimic acid derivatives by covering the important synthetic modifications and related applications, namely synthesis of protected (-)-gabosine E, (-)-MK7606, (-)-valienamine and finally unprotected methyl (-)-shikimate.
Deoxy-nitrosugars. Synthesis of Methyl Shikimate and of Diethyl Phosphashikimate from D-Ribose
Mirza, Sohail,Vasella, Andrea
, p. 1562 - 1567 (1984)
The chain elongation of the deoxy-nitroribose 6 by a Michael addition to the vinylphosphonate 7 followed by a solvolysis gave the heptulosephosphonate 11 (87percent).From 11, the key intermediates 15 and 16 (77percent) were obtained by a highly diastereos

Song, Chuanjun,Jiang, Shende,Singh, Gurdial
, p. 2833 - 2838 (2003)
(6S)-6-Fluoroshikimic acid 2 and (6R)-6-hydroxyshikimic acid 16 have been synthesised via an OsO4-catalysed dihydroxylation of diene 8, which was derived from (-)-shikimic acid 1.
An Electrophilic Natural Product Provides a Safe and Robust Odor Neutralization Approach to Counteract Malodorous Organosulfur Metabolites Encountered in Skunk Spray
Du, Lin,Munteanu, Charissa,King, Jarrod B.,Frantz, Doug E.,Cichewicz, Robert H.
supporting information, p. 1989 - 1999 (2019/08/20)
The anal secretions of skunks comprise several types of malodorous organosulfur compounds. The pungent metabolites are used defensively by skunks to repel threats posed by predators, and in many parts of the world, those perceived threats include humans a
Economical Process for Preparation of the 19-nor A Ring of Paricalcitol from (-)-Shikimic Acid
Zhou, Shengfeng,Zhu, Runyu,Hu, Jingwen,Zhang, Lixiong,Lu, Qian,Yu, Xinhong
, p. 1887 - 1891 (2019/08/26)
An economical and efficient means of preparing the 19-nor A ring, a key precursor of the vitamin D receptor (VDR) activator Paricalcitol, is here described. This process begins with commercially available (-)-shikimic acid and was easily scaled up to kilo
