[InlineMediaObject not available: see fulltext.] Use of azetidine scaffolds in stereoselective transformations (microreview)

[Figure not available: see fulltext.][InlineMediaObject not available: see fulltext.] Noteworthy stereoselective approaches toward the synthesis of densely substituted azetidines are reported. This microreview covers a selection of the latest efficient methods for the functionalization of azetidine cores by metalation, C–H activation, radical or biocatalytic processes, as well as nonclassical and large-scale preparative procedures.
