For the borodeuteride reduction of the aldehyde, employing THFA resulted in decreasing the isotopic purity of the corresponding alcohol because the deuteride of sodium borodeuteride could be exchanged with a proton from the alcohol: (a) Cornforth, R. H. Tetrahedron 1970, 26, 4635-4640. (b) Davis, R. E. ; Bromels, E.; Kibby, C. L. J. Am. Chem. Soc. 1962, 84, 885-892. Therefore, THFA-d was prepared and employed for the borodeuteride modification instead of THFA, and the product was obtained with a >95% deuteration degree.
