- W2034658991 abstract "An attempt was made to extend the total synthesis of (±)-aspidospermine (I) to the synthesis of (±)-limaspermine (IV). An eleven-step scheme starting from 5-phenoxypentan-2-one (XIV) gave (±)-21-phenoxyisopalosine (XXXIX), which was treated with hydrobromic acid to furnish the quaternary salt (XLII). The formation of this salt suggests that the stereochemistry of our products is not identical with that of the natural alkaloid." @default.
