A cyclovitamin D derivative produced from 25-hydroxyvitamin D is reacted with osmium tetraoxide or a permanganic acid salt to produce a 10,19-diolcyclovitamin D derivative. The 10,19-diolcyclovitamin D derivative is reacted with a perhalogenic acid salt or lead tetraacetate to produce a 10-oxocyclovitamin D derivative. A 1-hydroxycyclovitamin D derivative is produced from the 10-oxocyclovitamin D derivative via a cyclovitamin D derivative and a 1,10-olefincyclovitamin D derivative. The 1-hydrocyclovitamin D derivative is subjected to solvolysis, thereby producing a 1-hydroxy-19-norviatmin D derivative. Thus provided are a novel process for production of 1-hydroxy-19-norcyclovitamin D derivative that is utilizable as an intermediate in the synthesis of 1-hydroxy-19-norvitamin D derivative which is useful as a pharmaceutical agent; and an intermediate for the production.
