Abstract

Chiral Substituted 3-Formylfurans from Carbohydrates: An Expedient Route via N-Bromosuccinimide (NBS)-Mediated Electrophilic Cyclization. -The efficient and general method for the synthesis of the title furans involves a Heck coupling between substituted iodoenones and olefins followed by NBS-mediated electrophilic cyclization using H 2O as a nucleophile. The cyclization reactions of Heck products containing unactivated olefines lead only to traces of the desired products. -(MAL, K.; KAUR, A.; DAS*, I.; Asian J.
