Znâproline catalyzed aldolisation of glycoladehyde gave mainly tetroses whereas in the cross-aldolisation of glycoladehyde and rac-glyceraldehyde, pentoses accounted for 60% of the sugars formed with 20% of ribose.

Base-Pairing Systems Related to TNA: α-Threofuranosyl Oligonucleotides Containing Phosphoramidate Linkages<sup>1</sup>
[GRAPHIC](3'NH)- and (2'NH)-TNA, two isomeric phosphoramidate analogues of TNA (alpha-threofuranosyl-(3'-->2') oligonucleotides), are shown to be efficient Watson-Crick base-pairing systems and to undergo intersystem cross-pairing with TNA, RNA, and DNA.
