Benzyl trityl ether and DDQ as new tritylating reagents

We describe herein a new tritylation procedure of alcohols using benzyl trityl ether and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone. The reaction involves oxidative abstraction of one of the benzylic protons of benzyl trityl ether, followed by transformation of the generated benzyl trityl ether cation into a complex of benzaldehyde and trityl cation. The present procedure proceeds under mild neutral conditions to afford trityl ethers in generally good yields for primary alcohols, and in acceptable yields for several secondary alcohols.

Enantioselective Deuteration of β-Substituted α,β-Unsaturated Esters by Rhodium-1,2-Bis(2,5-diphenylphospholano)ethane

We report an efficient method for the synthesis of a chiral C-CHD-CHD-C unit in threo form, which enables the asymmetric conformational analysis of straight alkyl chains. The vicinal dideuterated compound was constructed by enantioselective catalytic deut

Synthesis, biological, and chiroptical activity of 3-phenyl-clavams

The [2+2]cycloaddition of chlorosulfonyl isocyanate to simple vinyl ethers derived from the 2-O-sulfonylated (R) and (S) 1-phenyl-1,2-ethanediol leads to 4-alkoxy-azetidin-2-ones with a moderate stereoselectivity. The cycloaddition to analogous (Z)-propenyl ethers proceeds stereospecifically with the retention of the olefin configuration. The intramolecular alkylation of β-lactam nitrogen atom furnished all possible stereoisomers of 3-phenyl- and 6-methyl-3-phenyl-clavams. The biological and chiroptical activity of synthesized clavams was investigated. The (3R,5R)-diastereomer 30 showed higher inhibition of bacterial enzymes than other related compounds.

Preparation of Chiral Diphenyl-Substituted Polyether-Diester Compounds

A new series of chiral polyether-diester ligands has been prepared by reacting racemic and chiral diphenyl-substituted tetraethylene glycols with diglycolyl chloride (5 and 6), 2,5-furandicarbonyl chloride (7 and 8), 2,6-pyridinedicarbonyl chloride (9-12), and 4-methoxy-2,6-pyridinedicarbonyl chloride (13).The chiral diphenyl-substituted tetraethylene glycols were prepared from the dl-, (S)-, and (R)-mandelic acids.
