P-Toluene sulfonic acid (PTSA)-MCM-41 as a green, efficient and reusable heterogeneous catalyst for the synthesis of jasminaldehyde under solvent-free condition

This paper reports the synthesis of p-Toluene sulfonic acid (PTSA)-MCM-41 by impregnation method and its characterization XRD, FT-IR, TGA, N2 adsorption-desorption isotherms, SEM, and TEM. The impregnated catalysts were used to catalyse cross-aldol condensation of active methylene bearing aliphatic aldehydes with aromatic aldehydes under solvent and metal-free condition particularly in the synthesis perfumery chemical-jasminaldehyde and related compounds. The as synthesized catalyst PTSA-MCM-41 has displayed high efficiency (selectivity up to 91%) in catalyzing cross-aldol condensation reaction and was reusable (5 cycles) with no apparent loss in activity. The catalytic performance of PTSA-MCM-41 was compared with other catalysts viz., ZnO, proline, proline-LDH, PTSA, PTSA-zirconia and PTSA-zeolite where PTSA-MCM-41 showed better performance particularly in synthesis of jasminaldehyde.

Highly enantioselective bioreduction of 2-fluorocinnamyl alcohols mediated by Saccharomyces cerevisiae

Biocatalytic reduction of 2-fluorocinnamyl alcohols mediated by Saccharomyces cerevisiae was investigated in phosphate buffer solutions. Product analysis clearly showed that (S)-2-fluoro-3-arylpropanols were afforded in high yields with up to 92% ee value.

Reactions of trimethylsilyl-derived iodohydrins with electron-rich π-systems

Reactions of trimethylsilyl-derived iodohydrins of the type R1R2CH-CH(I)OTMS, with electron-rich olefins, and the effects of certain factors on these reactions, were studied. The trimethylsilyl-derived iodohydrins were obtained in situ by reacting R1R2CH-CHO (R1 = R2 = H; R1 = H, R2 = alkyl, phenyl) with TMSI. The corresponding trimethylsilyl enol ether derivatives (R1R2C=CH-OTMS), and 1,1-diarylethylenes were the olefins used. Aldehydes of the type RCH2-CH=O reacted smoothly in the presence of TMSI to yield the condensation product RCH2-CH=C(R)-CH=O. Both RCH(-CH=CAr2)2 and the cyclic acetal 5 were obtained as main products of the RCH=O-TMSI-CH2=CAr2 reaction system, depending on the [RCHO]:[TMSI]:[CH2=CAr2] concentration ratio. The mechanisms of formation for the various main products and by-products are discussed. TMSI substitutes, formed by reacting Me3SiCl with each of several Lewis acids, were also used.
