Tt. Curran, PREPARATION OF ALPHA,ALPHA-DIFLUORO-BETA-HYDROXY ESTERS VIA A MODIFIED REFORMATSKY REACTION, Journal of organic chemistry, 58(23), 1993, pp. 6360-6363
A modified Reformatsky reaction has been developed which allows for th
e reproducible preparation of alpha,alpha-difluoro-beta-hydroxy- and g
amma-amino-alpha,alpha-difluoro-beta-hydroxy esters in good yield from
the corresponding aldehyde, ketone, or alpha-N-carbamoyl aldehyde.
