Synthesis of Resorcinols via a Michael Addition-Dieckman Cyclization Sequence of Dimethyl 1,3-Acetonedicarboxylate Anion with Alkyl Alkynoates
摘要:
The reaction of dimethyl 1,3-acetonedicarboxylate anion 1 with a number of alkyl alkynoates gives unsymmetrical (from alkynoates 2a-g) or symmetrical (from alkynoates 2h-i) resorcinols, in a one pot synthesis.

Three become one: The cationic rhodium(I) complex [Rh(cod)2]BF4 catalyzes the [2+2+1] cross‐cyclotrimerization of silylacetylenes and twoalkynylesters, leading to substitutedsilylfulvenes (see scheme; cod=1,5‐cyclooctadiene). The reductive complexation of the silylfulvene product with RhCl3 in EtOH furnished the corresponding dinuclear electron‐deficient cyclopentadienyl rhodium(III) complex.
