Electrochemical synthesis of a phosphorylated monomethano[60]fullerene
摘要:
61-(Dimethoxyphosphoryl)-61-(methoxycarbonyl)methano[60]fullerene was produced using the electrochemical reduction of fullerene C-60 and (dimethoxyphosphoryl)methoxycarbonyldibromomethane at a carbon felt electrode in the o-dichlorobenzene-DMF/0.1 M Bu4NBF4 system.

An organocatalytic dominoreaction consisting of Michael addition/intramolecular alkylation between α,β-unsaturated aldehydes and bromophosphonoacetates was developed. Highly functionalised cyclopropylphosphonates containing three chiral centres, one of them quaternary, were obtained with good diastereoselectivities of up to 83:17 and very high enantioselectivities of up to 99 %.
