Abstract
The work on developing a scalable lipase-catalytic method for the kinetic resolution of long-chain 1,2-alkanediols, complemented by crystallization of the pure enantiomers from the reaction mixtures, offered the possibility of a more detailed study of the aggregation of such diols. MD modeling, mass spectrometry, (1)H NMR, and DOSY studies provided a novel insight into the nucleation process. An efficient protocol for stereo- and chemoselective crystallization of (S)-1,2-dodecanediol and related compounds from the crude bioconversion mixtures was developed.
