Gembus, Vincent published the artcileRegioselective pinacol rearrangement of unsymmetrical cyclobutane-1,2-diols, Application In Synthesis of 517-23-7, the publication is Bulletin of the Chemical Society of Japan (2018), 91(3), 319-336, database is CAplus.
Hydroxy-sulfone I, prepared as a mixture of trans and cis isomers, was found to rearrange selectively either to the cyclopropanic β-ketosulfone II or the isomeric Me ketone III by using, resp., the tosyl fluoride/DBU and the DAST reagent. The potential of this methodol. has been illustrated by a synthesis of phytal from geranylacetone, and by the preparation from 3,4-hexanedione and prenol – via the cyclopropanic β-ketosulfone IV (X-ray) – of an advanced fragment of the juvenile hormone V.
