Oxazole– Carbonyl Photocycloadditions: Selectivity Pattern and Synthetic Route to erythro α-Amino, β-Hydroxy Ketones. — The photocycload- dition of aliphatic and aromatic aldehydes (IIa)–(IIc) with oxazole (I) proceeds highly regio- and stereoselectively to give bicyclic oxetanes (III). Hydrolytic cleavage of these adducts gives selectively erythro α-amino, β-hydroxy methyl ketones. — (GRIESBECK, AXEL G.; FIEGE, MAREN; LEX, JOHANN; Chem. Commun. (Cambridge) (2000) 7, 589-590; Inst.
