How if i use H2 and nickel catalyst. It's still possible right?Ya there was an amid but many people i think forgot to see because it was like proline form the cyclic amino acid type.
And for reduction u can use NaBH4 and LiAlH4 because NaBH4 can reduce ketones and aldehydes and since it was a ketone it could be reduced by NaBH4
You can use LiAlH4 also,Because it can reduce all of them including ester acid and ketone as well as aldehyde
Btw what was liposome one B then C or C then B?
