Total synthesis of myristinins A–F and 3′-hydroxy-5,7-dimethoxy-4-O-2′-cycloflavan by iterative generation of o-quinone methides

An iterative generation of o -quinone methides ( o -QMs) and [4+2] cycloaddition followed by inter/intra-molecular Michael addition in a cascade sequence gave expedient access to the total synthesis of myristinins A–F and 3′-hydroxy-5,7-dimethoxy-4- O -2′-cycloflavan and their analogues, respectively.
