The compounds are 1,4-disubstituted piperazines useful for the treatment of disorders of central nervous system and neuroendocrine disorders. A compound disclosed is (R,S)-4-(benzodioxan-5-yl)-1-[(benzocyclobutan-1-yl)methyl]piperazine.
We present herein the first oxidation of enynylboronates for the synthesis of γ-lactones, including spiro-, and fused-butanolides as well as butenolides that are prevalent in nature products and bioactive molecules. The asymmetric version of this oxidation was also achieved in the presence of chiral ketone and Oxone. This process successively involves the oxidation of C(sp)−B bond, the epoxidation
