An efficient heterogeneous catalytic method for the synthesis of α-hydroxy ketones from α-diazo carbonyl compounds 1, 3 and 6 in the presence of Amberlyst-15, a macro reticular ion exchange resin, is reported. The desired products were obtained at room temperature or by ultrasonication in good yield. Interestingly, novel fused 3-furanones and bicycloalkane-1,3-diones were obtained as unusual products in the case of alicyclic α-diazo carbonyl compounds.

A very mild method of decomposition of various α-diazo carbonyl compounds 1 in the presence of environmentally attractive solid acids such as montmorillonite K-10 or zeolite H-Y in a heterogeneous manner to furnish α-hydroxy/alkoxy ketones in very good yield is reported. Interestingly, novel bicycloalkane-1,3-diones and 3-furanones were obtained as unusual products in the case of aliphatic/alicyclic α-diazo carbonyl compounds.

Stannylallenes (1) reacted with α,β-unsaturated carbonyl compounds and α-nitro olefins in the presence of TiCl4 to give the corresponding conjugate propargylation products.Thus, the reaction of 1 with cyclic and acyclic α,β-unsaturated carbonyl compounds (2) gave β-propargylic ketones (3) in high yields.With α-nitro olefins (4), two types of products, β-propargylic nitroalkanes (5) and α-propargylic ketones (6), were obtained selectively depending on the presence or absence of the α-substituent of 4.Transformation of the products (6) to cyclopentenone derivatives (10 and 12) are also described.
