Key steps in the first total synthesis of Lacrimin A (2) include (a) the use of methoxyallene as an enone-1,3-dianion equivalent; (b) the use of a new copper-catalysed migratory insertion reaction to construct a tri-substituted alkene stereoselectively; and (c) the use of a Pd(O)-catalysed coupling reaction to generate an isochromanone ring.
