Efficient synthesis of t-butyl 3-alkyl-N-hydroxy-oxindole-3-carboxylates from di-t-butyl 2-nitrophenylmalonates
– A selective and efficient synthesis of t-butyl 3-alkyl-N-hydroxy-oxindole-3-carboxylates from di-t-butyl 2-nitrophenylmalonates is described. A tandem reduction-cyclization approach involving reduction of di-t-butyl 2-methyl-(2-nitrophenyl)malonate to d
Nucleophilic aromatic substitution using Et3SiH/cat. t-Bu-P4 as a system for nucleophile activation
A novel type of deprotonative arylation of nucleophiles was conducted using Et3SiH/cat. t-Bu-P4 and the powerful SNAr reactions of aryl fluorides were accomplished using alcohols and malonates as nucleophiles. The Royal Society of Ch
