Metal-free access to fully substituted skipped diynes. An efficient chemodifferentiating A2BB′ 4CR manifold

(Chemical Equation Presented) A metal-free chemodifferentiating A 2BB′ 4CR manifold for the modular synthesis of tertiary skipped diynes is described. The manifold performs a triethylamine triggered reaction of alkyl propiolates and acid chlori
