Tributylphosphine → HCID 15383948, compound

Participants

Reaction Steps

A procedure similar to that described in Preparation 6 was repeated, except that 0.52 g of 2(R)-[5(S)-(3-chlorophenoxymethyl)-2-oxooxazolidin-3-yl]propanol (prepared as described in Preparation 28), 1.01 g of 5-(4-hydroxybenzyl)-3-triphenylmethylthiazolidine-2,4-dione, 0.44 g of tributylphosphine, 0.55 g of azodicarbonyldipiperidine and 30 ml of anhydrous benzene were used, to give 1.02 g of the title compound having an Rf value of 0.26 (on silica gel thin layer chromatography, using a 1:1 by volume mixture of ethyl acetate and hexane as the developing solvent) and having [α]D =+35.9° (methanol, c=1.000).
