, p. 1887 - 1891 (2019)
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

The cis-dihydrodiol metabolite from methyl benzoate has been used as a synthetic precursor of carba-β-l-galactopyranose, carba-β-l- talopyranose and carba-α-l-talopyranose. The structures and absolute configurations of these carbasugars were determined by a combination of NMR spectroscopy, stereochemical correlation and X-ray crystallography.
