Optionally, acetate ester hydrolysis of intermediate (LVIII), followed by regioselective alcohol oxidation with Collin's reagent, yielded ketone (LX). The 7-hydroxyl group of (LX) was then protected by benzylation to afford (LXI). Reductive amination of ketone (LXI) with the di-Boc-protected spermidine (XL) provided the polyamino sterol (LXII). After hydrolysis of the ethylidene ketal group of (LXII), the resultant ketone was reduced by NaBH4 to give alcohol (LXIII).
