A new class of chiral C 2 -symmetric dipyridylmethane ligands was prepared from naturally occurring monoterpenes, according to a method based on a double Michael-azaannellation-aromatization sequence. These ligands were assessed in the enantioselective palladium-catalyzed allylic alkylation of 1,3-d
A nonsymmetric Bush-type Hadamard matrix of order 36 is constructed which leads to two new infinite classes of symmetric designs with parameters: where m is any positive integer.
An embedding theorem for certain quasi-residual designs is proved and is used to construct a series of symmetric designs with v = (1 + 16 + ... + 16")9 + 16 "+~, k =(1 + 16 + ... + 16m)9, and 2 = (1 + 16 + ... + 16m-~)9 + 16".3, for a non-negative integer m.
