Abstract
Abstract (±)-1-Benzyl-3α-hydroxy-4β-methylamino-2-oxopyrrolidine ( 15 ) and its cis -isomer ( 16 ) were synthesised from 1-benzyl-4-ethoxycarbonyl-2,3-dioxopyrrolidine ( 2 ) in several steps. The former ( 15 ) was converted to 3-benzyl-6-methyl-2-oxo-3,6-diazabicyclo[3.1.0]hexane ( 17 ) with a mixture of triphenylphosphine, carbon tetrachloride and triethylamine.
