Synthesis of 2-alkylisoflavones under phase-transfer catalysis conditions
2-alkyl isoflavones were synthesised with the aliphatic acid chloride and 2-hydroxydeoxybenzoins under phase-transfer catalysis in acetone-K 2CO3 medium involves the modified Baker-VenKataraman transformation.

A comparative study of the epoxidation of 2-substituted isoflavones by dimethyldioxirane, sodium hypochlorite, and alkaline hydrogen peroxide (Weitz-Scheffer reaction)
The comparative epoxidation of 2-substituted isoflavones 9-16 has been conducted by the utilization of three different protocols, viz. epoxidation with isolated dimethyldioxirane (Method A), with sodium hypochlorite (Method B), and with alkaline hydrogen peroxide (Method C), to afford epoxides 17-24. Best results have been obtained with Method C (Weitz-Scheffer epoxidation). The structures of epoxides have been assigned on the basis of nmr spectral and mass spectral data.
