Spirocyclohexadienones: XII. Dienone-phenol rearrangement of 1-substituted 2-azaspiro[4.5]undeca-1,6,9-trienes and their analogs
摘要:
Hydrolytic cleavage of 1-substituted 2-azaspiro[4.5]undeca-1,6,9-trienes in acid medium is accompanied by dienone-phenole rearrangement with formation of substituted N-[2-(p-hydroxyphenyl)ethyl] carboxylic acid amides. 1,2-Dimethoxy-3-oxo-15-phenyl-14-azadispiro[5.1.5.2]pentadeca-1,4,14-triene and 2'-R-7a'-methyl-3a',4',5',6',7',7a'-hexahydrospiro[cyclohexa[2,5]diene-1,3'-indol]-4-ones undergo analogous cleavage.
