Article abstract of DOI:10.1016/0957-4166(95)00073-X

The chiral β-amino alcohols-catalyzed addition of diisopropylzinc to steroidal 24-aldehydes successfully provided 24(R)-hydroxycholesterols in good yields with high diastereoselectivities, which are synthetic intermediates of 1α-24(R)-dihydroxyvitamin D3
