โœฆ Synopsis

Unstable intermediates containing a (p -P)~ bond between y;bon and another element, for example, silicon-carbon', gewanium-carbon * , phosphorus-carbon4, sulfur-carbon5 are of considerable theoretical interest. One of the8e, methylenimine (1) is the prototype of nitrogen-carbon double bonded compOund8.

Together with formaldehyde and thiofoxmaldehyde this compound ha6 been detected in interstellar space6. It was also observed in a gflo phase under low pressure (nriCrOwaVe7*8, photoelectron9 and ma88 SpeCtFCel?y ) and in the rare gas matrices at 4 K (ir spectroscopy) USil43 pyrolysis of rethylaeide, pyrolysis of methylamine6v8

## Abstract A short access to novel azetidineโ€derived __anti__โ€1,2โ€diamines starting from easily accessible 2โ€cyanoazetidines has been developed. A oneโ€pot sequence, including a nucleophilic addition and reduction of the resulting imine, allows for a diastereoselective synthesis of variously substi
