A diastereoselective approach to cis- and trans-1,3-disubstituted bicyclo[2.1.0]pentanes (housanes) was recently reported by our chemists in The Journal of Organic Chemistry. The article included preparation of 35 derivatives on up to 100 g scale. Moreover, pKa’s and conformational features of selected examples of housanes (e.g. GABA analogues) were also studied and compared to that of the corresponding 1,3-disubstituted cyclopentanes.
