Rhodium (I)-catalyzed cyclizations of 3-C-alkenyl pentodialdose derivatives
摘要:
Cyclization of 1,2-isopropylidene 3-C-allyl ribo-pentodialdose, and 1-methylallyl and 3-C-vinyl analogs, with [(Ph3P)2RhCl]2 under CH2CH2 leads to intramolecular hydroacylation of the alkene with selective formation of cyclohexanones or cyclopentanones.
