Silica supported phosphotungstic acid functionalized with triphenyl(3-sulfopropyl)phosphonium (PW-Si/TPSP) was developed as a solid acid catalyst for C-C bond formation via Hosomi-Sakurai allylation of acetals. Functionalization of PW as well as its bindi

A mesoporous aluminosilicate (Al-MCM-41) was found to be an effective heterogeneous catalyst for the reaction of both carbonyl compounds and acetals with allylsilanes to afford the corresponding homoallyl silyl ethers and homoallyl alkyl ethers, respectively. Both the mesoporous structure and the presence of aluminum moiety were indispensable for the high catalytic activity of Al-MCM-41. Moreover, Al-MCM-41 could catalyze the reaction of acetals chemoselectively in the presence of the corresponding carbonyl compounds. The solid acid catalyst Al-MCM-41 could be recovered easily by filtration and could be reused three times without a significant loss of catalytic activity.

In the presence of a catalytic amount of mesoporous aluminosilicate (Al-MCM-41), both allyltrimethylsilane and silyl enol ether reacted with various acetals under mild reaction conditions to afford the corresponding homoallyl ethers and β-alkoxy ketones,

The electrochemical cyclization of a series of ortho-halo-substituted homoallyl ethers and esters to functionalized indanes catalyzed by Ni(II) catalyst precursors derived from Ni(cyclam)Br2, (cyclam = 1,4,8,11-tetraazacyclotetradecane) and Ni(tmc)Br2, (tmc = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) is reported. The starting homoallyl ethers were synthesized using either a one-pot method for allylation of aldehydes or by direct allylation of the corresponding acetals using bismuth triflate as a catalyst. The remarkably low toxicity, low cost and ease of handling of bismuth salts coupled with the mild nature of the electrochemical procedure makes this approach to indane synthesis especially environmentally friendly and attractive.

Systematic SAR studies on the thiazole ring 5-substituent of TCAT derivatives revealed that the introduction of a β-alkoxy or an amino group enhanced the inhibitory activity significantly. The present compounds are representative of specific Co(II)-MetAP1 inhibitors. Before the physiologically relevant metal ions for MetAPs are established, these small molecular compounds could be used as tools for detailed biological studies.
Scandium triflate catalyzed allylation of acetals and gem-diacetates: A facile synthesis of homoallyl ethers and acetates
