Racemic cis-1-methoxycarbonyl-2-methylcyclobutane uncontaminated with the trans isomer was prepared efficiently in five steps; the corresponding amides from (R)-(-)-phenylglycinol were separated. An X-ray crystallographic structure determination of the amide from (+)-cis-1-methoxycarbonyl-2-methylcyclobutane showed that it was of (1R,2S) absolute stereochemistry, a revision of configurational assignment
