Ln(III)trifluoromethansulfonates in CH2Cl2 efficiently catalyze the aminolysis of trimethylene oxide, 2-octyl-, and 2-phenyloxetane, at r.t., to give the corresponding γ-amino alcohols in very good yields.

perruthenate, with NMO provide N,O‐acetal moieties by trapping the resulting iminium ion with the alcohol. These two transformations were demonstrated in the protecting group free synthesis of indolizidines (–)‐223AB and 3‐epi‐(–)‐223AB, compounds found in dart‐frog poison.
