What are you asking here? Reducing agent? Reaction mechanism? Do you know any reagents that might transform an ester into an alcohol?

As long as everyone's handing out ideas for free: LiBH4 with catalytic methanol in Et2O. Works like a charm when sensitive functional groups are around.

Do you get any reaction products, or do you just get the starting material back after the reaction? Maybe the phosphorine ring isn't stable under the common hydride conditions (or maybe it is, I've never used it or known it being used).

I really got some products, from TLC analysis, I found many pots and there was one lagging from starting line to the end.How can I got what I need? friend if you have any new ideas, please impress me, maybe we can really become friend.
