Base catalysed Isomerisation of 3-Benzylidene-4-chromanones: Formation of 3-Methylflavones
Jain, A. C.,Sharma, Anita,Singh, Bikram
, p. 759 - 761 (2007/10/02)
3-Benzylidene-4-chromanones having even 7-methoxy- or 7-benzyloxy-group undergo isomerisation in the presence of alkali to give the corresponding 3-methylflavones besides the normal 3-benzylchromones.This observation differs from that made by Donelly et a
Homoisoflavones: Part V - Bromination of 3-Benzylchroman-4-ones
Chatterjea, J. N.,Singh, R. P.,Jha, I. S.,Shaw, S. C.
, p. 923 - 924 (2007/10/02)
Bromination of 3-benzylchroman-4-ones (IIa-e) with cupric bromide or phenyltrimethylammonium perbromide affords the 3-bromo derivatives (IIIa-e) which have been conveniently converted into homoisoflavones (Va-e).) Bromination of IIa-e with N-bromosuccinim
