Message definition (Vitamin D5)
1α-Hydroxyvitamin D<sub>5</sub> was first synthesized in 1997 by researchers in the Department of Chemistry at the [[University of Chicago]], under Robert M. Moriarty and Dragos Albinescu. By 2005, the group had revised its synthesis method for a more streamlined, higher yield-producing route. It involved the photochemical conversion of precursor [[7-Dehydrositosterol|7-dehydrositosteryl]] acetate to contain a conjugated triene system, a hallmark of this analog, followed by [[hydroxylation]], [[photoisomerization]], and [[Protecting group|deprotection]] steps. Their overall yield was 48%.

By 2005, the group had revised its synthesis method for a more streamlined, higher yield-producing route. It involved the photochemical conversion of precursor 7-dehydrositosteryl acetate to contain a conjugated triene system, a hallmark of this analog, followed by hydroxylation, photoisomerization, and deprotection steps. Their overall yield was 48%.
