Labor is comparable for the two processes. The overall yield of lactol 6a from chlorobenzene was 45 %. This compares with a yield of 39% from arabinose
-
A realistic cost estimate for lactols 6a and 6b is $2.40/g from arabinoses, and $1.40/g from chlorobenzene. Labor is comparable for the two processes. The overall yield of lactol 6a from chlorobenzene was 45 %. This compares with a yield of 39% from arabinose.

All nonhydrolytic reactions were carried out in a nitrogen or argon atmosphere, with standard techniques for the exclusion of air and moisture
-
THF, ethyl ether, DME, and benzene were distilled from benzophenone ketyl, dichloromethane, and toluene from calcium hydride. Analytical TLC was performed on silica gel 60F-254 plates. Flash chromatography was performed using Kieselgel 60 (230–400 mesh). Mass spectra were recorded on a DuPont 20–491 or a Varian MAT-112 instrument (low resolution) or on a double-focusing DuPont 21-110C or VGT instrument (exact mass). Infrared spectra were recorded as neat samples (NaCl plates) on a Perkin-Elmer 1600 Series FT spectrometer. Proton NMR spectra were obtained on a Bruker WP-270 instrument. Proton chemical shifts are reported in parts per million (ppm) relative to chloroform (7.24 ppm). Carbon NMR spectra were recorded on a Bruker WP-270 instrument. Carbon chemical shifts are reported in parts per million relative to the center line of the CDC13 triplet (77.0 ppm). The multiplicity is indicated by CH3, CH2, CH, or C and were determined by INEPT
