A process for preparing the (R) stereoisomer of 2,2-bis(hydroxmethyl)-tetrahydrofuran monobutyrate comprising subjecting the dibutyric ester of the 2,2-bis(hydroxymethyl)-tetrahydrofuran to enzymatic hydrolysis. The invention also relates to the novel (R) stereoisomer prepared by the instant process and to its more stable forms. In addition, the invention relates to the use of the (R) stereoisomer in preparing stereoisomers of pharmacologically active compounds and to certain specific stereoisomers produced thereby.
