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.
