A versatile asymmetricsynthesis of 3-substituted azetidine-2-carboxylic acids and 2-substituted azetidine-3-carboxylic acids via 1.3-amino alcohols with excellent stereoselectivities (de > 96%, ee > 96%) is reponed. The high asymmetric inductions were achieved employing the SAMP/RAMP-hydrazone methodology. A phenyl moiety was used as a synthetic equivalent of the carboxylic acid function. In addition
