10-Methylacridinium perchlorate (1) effectively promotes various reactions of ketene silyl acetals: aldol and Michael addition products are obtained with aldehydes, ketones, acetals, and α-enones.The reactions exhibit unusual dependency upon 1, namely the yields are excellent when a catalytic amount of 1 is employed whereas no desired products are accessible by the use of 1 in a stoichiometric quantity.A novel catalytic cycle is proposed.

Anodic oxidation of β-ethylenic esters yields butenolides 2.In the presence of 1-phenyl-1-propene or α,β-disubstituted indenones a double cyclization takes place to yield more complex butenolides
