alpha-Hydroxypropargylsilanes undergo rearrangement to form reactive lithium allenolates. The resulting alpha-acylvinyl anion equivalents undergo highly selective additions to N-tert-butanesulfinyl imines generating beta-substituted aza-MBH-type products. High yields are achieved for a wide range of alpha-hydroxypropargylsilanes as well as for a diverse selection of imines. The reactions proceed with good
