A Carbon-Carbon Bond Formation by the Reaction of 4-Chloro-6-methyl-3-phenylethynyl-2H-pyran-2-one with Active Methylene Derivatives
摘要:
The reaction of 4-chloro-6-methyl-3-phenylethynyl-2H-pyran-2-one (2) with compounds containing active methylene group, such as diethyl malonate, acetylacetone, ethyl cyanoacetate, and malononitrile, in the presence of NaH gives 4-substituted 6-methyl-3-phenylethynyl-2H-pyran-2-one(3) and/or 6-methyl-3-phenylacetyl-2H-pyran-2-one (5).
