Study of chiral β-enaminones prepared from pyrrolidine, cytisine, salsoline and 2-amino-1-(4-nitrophenyl)propane-1,3-diol: resolution of salsoline via diastereomeric modified carane-type β-enaminones

Add time:09/10/2019    Source:sciencedirect.com

A series of novel optically active β-enaminones have been prepared regio- and stereoselectively from primary and secondary amines (pyrrolidine, cytisine salsoline and 2-amino-1-(4-nitrophenyl)propane-1,3-diol) and (+)-3-carene-derived β-chlorovinylketone. Resolution of the isoquinoline alkaloid salsoline has been demonstrated as well as isolation of a single diastereomeric adduct from racemic 2-amino-1-(4-nitrophenyl)propane-1,3-diol.
