Page/Page column 53-54, (2009/09/28)
The present invention relates to azetidine and cyclobutane derivatives, as well as their compositions, methods of use, and processes for preparation, which are JAK inhibitors useful in the treatment of JAK-associated diseases including, for example, inflammatory and autoimmune disorders, as well as cancer.
Synthesis of conformationally restricted glutamic acid analogs based on the spiro[3.3]heptane scaffold
Radchenko, Dmytro S.,Grygorenko, Oleksandr O.,Komarov, Igor V.
experimental part, p. 2924 - 2930 (2009/07/04)
A library of isomeric glutamic acid analogs based on the spiro[3.3]heptane skeleton is designed. Two members of the library, (R)- and (S)-2-amino-spiro[3.3]heptane-2,6-dicarboxylic acid hydrochlorides, were synthesized. The stereochemistry of the synthesi

3,3-Di(isopropoxycarbonyl)-1,1-dimethoxycyclobutane (1) was converted, in multi-steps, to 3-(1,3-dithiacyclohex-2-yl)-1,1-di(p-tosyloxymethyl)cyclobutane (7), which was subjected to a butyllithium-mediated cyclization to give the bicyclo[2,1,1]hexane ring system 8. Further transformations afforded 1-(t-butyldimethylsilyloxymethyl)-3(R,S)-hydroxybicyclo[2,1,1]hexanes (11), which were condensed with 6-chloropurine and 4-acetylcytosine via Mitsunobu reactions to give, after further treatment, 3(R,S)-(adenin-9-yl)- and 3(R,S)-(cytosin-1-yl)-1-hydroxymethylbicyclo[2,1,1]hexanes (14 and 17), respectively.
