Homochiral cis, cis‐; cis,trans and trans,trans‐spiro [4,4]‐nonane‐1,6‐diols were prepared via diastereoselective reduction of enantiomerically pure spiro[4.4]nonane‐l,6‐dione (1) with the corresponding reducing agents: lithium n‐butyldiisobutylaluminium hydride for cis,cis ‐diol (2) with 88% yield; BH 3 ·THF for cis, trans ‐diol (8) with 91% yield; LiAlH 4 for trans,trans ‐diol (4) with 15% yield.
