A novel approach for the asymmetric synthesis of the active (1S,2R)-enantiomer of the antidepressant milnacipran is reported. The two stereogenic centers borne by the cyclopropane ring were sequentially installed starting from phenylacetic acid.

In the presence of a catalytic amount of TsOH or TiCl4, (Z)-5-silyl-4-penten-1-ols ((Z)-1) are smoothly cyclized to 2-silylmethyl-substituted tetrahydrofurans. This cyclization is applicable to the construction of a tetrahydropyran ring. The silyl group and the geometry of the C-C double bond strongly influence the cychzation rate. TBDMS and benzyldimethylsilyl groups considerably accelerate the cyclization in comparison with a dimethylphenylsilyl group, and (E)-vinylsilanes show much lower reactivity than the corresponding (Z)-isomers. The cyclization proceeds by stereospecific syn addition of the hydroxy group. Vinylsilanes 17, 19, and 21, (Z)-5-silyl-4-penten-1-ols bearing a substituent on the methylene tether, smoothly undergo the acid-catalyzed cyclization to give trans-2,5-, cis-2,4-, and trans-2,3-disubstituted tetrahydrofurans, respectively, with moderate to high stereoselectivity. The silyl group of some cychzed products can be easily converted into a hydroxy group with stereochemical retention.
5-(Aminomethyl)-3-aryldihydrofuran-2(3H)-ones, a New Class of Monoamine Oxidase-B Inactivators

Both cis- and trans-5-(aminomethyl)-3-aryldihydrofuran-2(3H)-one hydrochloride salts (9 and 10) were synthesized efficiently in a 5-step sequence from arylacetic acids.Both compounds were found to be irreversible inactivators of monoamine oxidase B.These
AN EFFICIENT ROUTE TO 1,3-AMINO HYDROXYL SYSTEM VIA ELECTROPHILIC LACTONIZATION OF 2-AMINO-4-PENTENOIC ACID DERIVATIVES. STEREOSELECTIVE SYNTHESIS OF (-)-BULGECININE

Several γ-hydroxy-α-amino acid systems were prepared stereoselectively from 2-amino-4-pentenoic acid derivatives using electrophilic lactonization.This strategy was applied to the synthesis of a highly functionalized proline analogue, (-)-bulgecinine (4).
