THE SYNTHESIS OF LUPIN ALKALOIDS. I. TOTAL SYNTHESIS OF (±) -LEONTIFORMINE AND (±) -LEONTIFORMIDINE

抄録

The novel total synthesis of the lupin alkaloids (±) -leontiformine (1) and (±) -leontiformidine (2) has been achieved by using the 1, 3-dipolar cycloaddition reaction of 1-piperine 1-oxide (4) twice in the synthesis process.
