Coumarane-3-ones

Coumaran-3-one without substitution at the 2-position can be synthesized by oxidation of silyl enol ether 62 with iodosobenzene under Lewis acid conditions. a-Hydroxyketone 63 is formed as a side product (86SC1239). [Pg.21]

Coumarane-3-ones.2 Oxidation of o-hydroxyphenyl alkyl ketones with QH OAc results in 2,2-dimethoxycoumarane-3-ones (2). [Pg.385]

The reactions of coumaran-3-ones 276 and 278 with tetrazines 1 were used for the preparation of the pyridazino-fused analogs 277 and 279 (Scheme 68) <2002SL2095, 2002S43>. [Pg.684]

Intramolecular participation by the ortho hydroxy group occurs in the reaction of substituted o-hydroxyacetophenones, yielding the corresponding coumaran-3-ones (eq 12). ... [Pg.137]
