Introduction

Glyceraldehyde acetonide (2,3-O-isopropylidene-d-gly­ceraldehyde, 1) it is a well-known chiron which has been used in organic synthesis for multiple purposes. [¹] It has been applied on the synthesis of a β-adrenergic antagonist, [²] on multicomponent reaction in the synthesis of ­nakadomarin A precursor, [³] and reacts with several organometallics to afford chiral alcohols used as precursors in total syntheses. [4-7] Its R isomer is easily prepared from selective protection and oxidative cleavage of ­in­expensive and available commercially d-mannitol (Scheme  [¹] ) [8] and its enantiomer can be obtained from vitamin C. [9] The present Spotlight emphasises recent applications of this chiron in organic synthesis in its R and S enantiomeric forms.
