Organic building blocks : From a starting material of electron‐deficient 1,3‐conjugate enynes 1 (see scheme; EWG=electron‐withdrawing group), it is possible to make three types of useful organic building blocks (1,2‐allenes, 1,3‐dienes, and 4 H ‐pyrans) regioselectively, by a simple choice of different nucleophiles.
