In the course of our exploration of the application of mucohalic acids in organic synthesis, we reported the synthesis of α,β-dihalo-α,β-unsaturated γ-butyrolactams by reductive amination of a suitable mucohalic acid and a suitable amine. Howeve

A simple and efficient methodology has been developed for the synthesis of methyl 3,5-diaryl-isoxazoline-5-carboxylates in a high-throughput fashion. This was accomplished in one-pot by a sequence of three 2-component reactions steps (2·2·2-CR), wh

A catalyst composed of (R,R)-MeDuphos and CuBr·SMe2 catalyzes the addition of RMgBr (R = Et, C5H11, Ph) to simple enamides (E)-Me2NCOCH CHR1 (R1 = Me, C5H11) in acceptable yields (50–78%), but with poor to modest enantioselectivities (0–74% ee).

An acid- and base-stable protecting group for carboxylic acids is described. The esters of (2,6-dichloro-4-methoxyphenyl)(2,4-dichlorophenyl)methanol are stable to Bronsted and Lewis acids, Bronsted bases, and a wide variety of nucleophiles; however,
