I have some problems with making a connection in order to reach the final product of my synthesis.
I want to connect and amide an aldehyde thought a nucleophilic addition in order to get an N, O-alcohol product (Hemiaminal).
could you please give some advice? I have been trying to make that connection for a month using several papers but none of them lead me to the product.
Thank you very much in advance for your propositions
