Unexpected formation of new chiral 3-amino-5-alkyl-2,5-dihydro-1H-pyrrolin-2-ones from N-Boc-alpha-amino esters
We describe a one-pot process involving the DiBA1-H reduction of the ester moiety of N-protected α-amino esters, followed by Horner-Wadsworth-Emmons olefination in the presence of the trimethyl ester phosphonoglycinate carbanion allowing the formation of new chiral 3-amino-5-alkyl-2,5-dihydro-IH pyrrolin-2-one 5. The Z-enoate 4b, which is formed during this reaction, could be converted into the corresponding lactam 5b under UV irradiation with the presence of BuLi. © 2005 Elsevier Ltd. All rights reserved.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 20880-92-6. SDS of cas: 20880-92-6.
