1α-Hydroxy-19-nor-vitamin D C-22 aldehyde. A valuable intermediate in the synthesis of side chain modifed 1α,25-dihydroxy-19-nor-vitamin D3
摘要:
A side chain homologated 1-alpha,25-dihydroxy-19-nor-vitamin D3 analog was prepared in a double convergent synthesis with 1-alpha-hydroxy-19-nor-vitamin D C-22 aldehyde as a key intermediate.
