Synthesis of the diazepanone-nucleoside portion of liposidomycins by aldol reaction of the enolate of diazepanone with a nucleoside 5′-aldehyde
摘要:
The diazepanone-nucleoside part of liposidomycins has been synthesized by the aldol reaction between the enolate of a stereochemically defined diazepanone and a uridine 5'-aldehyde. The configurations of two new stereocenters in the aldol product have been assigned on the basis of the H-1 NMR coupling constants and NOE of its derivative. (C) 1998 Elsevier Science Ltd.
