Abstract
The synthesis of an (S,S)-2-oxo-2-propionyl-1,3,2-oxazaphosphorinane, via the condensation of (S)- 1 -N-isopropylbutan-2-ol (3) with methyl dichloro phosphite (CH3OPCl2) followed by the Michaelis-Arbusov condensation reaction with propionyl chloride, will be described. We will also present the results of OUT investigations which describe the nature of the aldol reaction involving the enolate of oxazaphosphorinane 5 with benzaldehyde.
