The present invention includes a number of novel intermediates such as the (S)-secondary alcohol of formula (VIIIA)
X2—CH2—C*H(OH)—CH2—NH—CO—RN (VIIIA)
and processes for production of pharmacologically useful oxazolidinones.
The regioselective synthesis of several aminoepoxides has beenachieved without observing any trace of azetidinols, which are usuallyreported as the exclusive reaction products when aminohalohydrinsare treated with bases. The use of the mild supported base KF-Celitein refluxing acetonitrile is crucial for modulating the excellentregioselectivity observed.

for the preparation of linezolid in particular, a more convergent and versatile synthesis was developed for the rapid preparation of numerous other oxazolidinone analogues. Toward this end, economical methods for the large-scale preparation of N-[(2S)-2-(acetyloxy)-3-chloropropyl]acetamide 3 and tert-butyl [(2S)-3-chloro-2-hydroxypropyl]carbamate 27 from commercially available (S)-epichlorohydrin via
