Enamine synthesis of aldehydes and ketones ; An aldehyde or ketone is reacted with a secondary amine to form an enamine. The enamine reacts as the nucleophile in an SN2 Our plan at this point was to append the desired acetate side chain to the lactam nitrogen and then functionalize at C-3 via a lithium dianion. While alkylation of 17 with BrCH2CO2Et was successful (LiN (TMS)2, THF, 70%), several attempts to form a dianion of the resulting lactam-ester failed. cabinet suppliers near me
