Synthesis of α-amino ketones and O-alkyloximes has been developed by titanium tetrahalide-promoted ring-opening reactions of 2-mono-substituted azetidin-3-ones and their O-alkyloximes. Regarding the reductive ring-opening reactions of 2-mono-substituted azetidin-3-ones, an appropriate use of TiI 4 or TiI4-TiCl4 as a promoter gave α-amino ketones in good yields with high regioselectivities. In TiBr4-promoted ring-opening reactions, while use of 2-mono-substituted azetidin-3-ones as a substrate provided α-amino-α'-bromo ketones generated by the attack of the bromide anion at the less hindered site, those of 2-mono-substituted azetidin-3-one O-alkyloximes proceeded at the more hindered site to give α-amino-α'-bromo ketone O-alkyloximes in good yields.

A series of unsaturated α-amino alcohols were prepared via the allylboration of the corresponding N-protected α-amino ketones.The reactions are stereoselective, producing the syn isomers.The diastereoselectivity is not dramatically affected by the electro
