Photochemical reaction of 5-azido-2-methoxy-3-methyl-1,4-benzoquinone with cis,cis-2,4-hexadien-1,6-diol derivatives stereoselectively affords the corresponding 2,3-dihydroindolquinone, which possesses trans configuration at 2,3-position and vinylic double bond preserves the original stereochemistry of the diene.It is efficiently converted to a key precursor in mitomycin synthesis.

The invention is directed to a process for preparing a 1,4-disubstituted cyclohexane compound of formula (I): where A is —OH, —OR, Br, or Cl; and R is a silyl group, a hydrocarbyl group, or an acyl group having 1 to 12 carbon atoms. The process includes the steps of reacting ethylene with a (2E,4E)-hexa-2,4-diene compound to produce a 3,6-disubstituted cyclohex-1-ene compound, and hydrogenating the 3,6-disubstituted cyclohex-1-ene compound to yield the 1,4-disubstituted cyclohexane compound of formula (I).

A highly efficient method for the enantioselective synthesis of 1,4-dienes (skipped dienes) with a methyl-substituted central stereogenic carbon using copper-catalysed asymmetric allylic alkylation of diene bromides was developed. Excellent regio- and enantioselectivity (up to 97 : 3 SN2′/ SN2 ratio and 99% ee) were achieved with broad substrate scope. The Royal Society of Chemistry 2013.
