METHOD OF PRODUCING 2-HYDROXYBUTYROLACTONE

摘要

FIELD: chemistry.SUBSTANCE: invention relates to a process for preparing 2-hydroxybutyrolactone (2HBL) from the compound of formula (I) CH-S-CHCHCRIR2R3, wherein first a sulfone of formula (II) [CH] [CHCHCR1R2CR3] [CR6R7R8] SX, and the resulting sulfonium hydrolyzed, and 2,4-dihydrohydroxy-butanoic acid acid or salt thereof is cyclized to 2-hydroxybutyrolactone (2HBL).EFFECT: technical result developed a new, more simple, inexpensive and effective method for the synthesis of 2-hydroxybutyrolactone (2HBL).9 cl, 5 tbl, 5 ex
