References and Notes
General Procedure for Glycoporphyrins (6 and 7)
A solution of the metalloporphyrin (0.04 mmol) and Grubbs catalyst 2 (25% mol, 0.01 mmol) in degassed dry CH2Cl2 (2 mL) was heated at reflux, under argon, and the allyl sugar 5, dissolved in CH2Cl2 (1 mL), was immediately added by a syringe to the mixture. The reflux was kept as mentioned in Table
[1]
. The solvent was evaporated and the residue was purified by flash chromatography using a gradient of toluene-EtOAc as the eluent. The products 6 and 7 were obtained as red solids after crystallization from PE.
