Chiral 2,3-epoxy aldehydes have been effectively utilized for the first time as novel electrophiles in Baylis–Hillman reactions with activated alkenes to result in densely functionalized adducts in good yields (61–80%) and in moderate to good diastereoselectivities (40–72% de).

A diastereoselective three-component Passerini reaction (P-3CR) of chiral 2,3-epoxy aldehydes with tosylmethyl isocyanide (TosMIC) under benzoic acid conditions to afford densely substituted products in moderate to good yields and diastereomeric excess is reported.
