H(2)O. Stereoselective addition of the allenylindium to aliphatic or aromatic aldehydes affords 1,3-aminoalcohols bearing three contiguous chiral centers: while 2,3-trans-2-ethynylaziridines yield syn,syn-2-ethynyl-1,3-amino alcohols predominantly, 2,3-cis-aziridines give anti,syn isomers selectively. Synthesis of highly substituted ethynylazetidines is also described.
