Cyclobutane Derivatives

Enantioselective synthesis of cyclobutane derivatives is still a challenging topic in asymmetric synthesis. [2+2]-Cycloaddition and skeleton rearrangement are two primary strategies to this end. Recently, functionalization of cyclobutanones and cyclobutenones, which are readily available via [2+2]-cycloadditions as prochiral substrates, has emerged as a powerful tool to access versatile four-membered ring compounds. Herein, we summarize some recent advances in these areas from our and other groups.

Cyclobutane Derivatives

Ultraviolet irradiation of 3-(p-anisyl)-2-cyclohexenone and 3-(p-nitrophenyl)-2-cyclohexenone has been found to give a single photodimer in each case, the structures of which have been established as the cis–anti–cis head-to-head cyclobutane derivatives XI and XIII, respectively.
