  Studies on the diastereoselective allylation of aldehydes with enantiopure 2-sulfinylallyl building blocks

  摘要：

  A comparative study on the allylation of aldehydes with enantiopure (S-S)-2-(p-tolylsulfonyl)-prop-2-en-1-ol (S-S)-1a and the corresponding chloride (S-S)-1b under two different reaction systems is reported. In general, better yields were obtained from chloride (S-S)-1b, whereas higher diastereoinduction was observed from alcohol (S-S)-1a. The sense of diastereoinduction is the same in both systems and the stereochemistry of the major diastereomer has been determined. Moreover, the configurational stability of the sulfoxide group on the resulting sulfinyl homoallylic alcohols 3 has been proven in each reaction system. which demonstrates the efficiency of the sulfoxide group as chiral auxiliary in these allylation processes. Finally. as an example of the synthetic potential of the resulting adducts, a total synthesis of natural enantioenriched (S)-nicotine from sulfinylalcohol 3h is reported, (C) 2001 Elsevier Science Ltd.

  p-Tolylsulfinyl Amides:  Reagents for Facile Electrophilic Functionalization of Olefins

  摘要：

  A variety of olefins were found to react with sulfinyl amides in the presence of POCl3 to give beta-chlorosulfides and beta-hydroxysulfides in good yields. In the absence of nucleophiles, p-tolylsulfinyl amides were found to react with olefins with the formation of allylsulfoxides.

Besides the successful selenenylation reactions, one selenium electrophile showed an unexpected reactivity in forming a six-membered heterocyclic system upon reaction with alkenes. A mechanism for the formation of these 2,3-dihydro-1,4-benzoselenothiine 1-oxides is proposed

  The enantioselective synthesis of isochroman motifs has been accomplished by palladium(II)‐catalyzed allylic C−H oxidation from terminal olefin precursors. Critical to the success of this goal was the development and utilization of a novel chiral aryl sulfoxide‐oxazoline (ArSOX) ligand. The allylic C−H oxidation reaction proceeds with the broadest scope and highest levels of asymmetric induction reported

The most active racemic compound, 6al (R4 = isobutyl; R = ethoxy), turned out to be 12 times more active than the sulfonylurea (SU) glibenclamide (1). Activity was found to reside predominantly in the (S)-enantiomers. Compared with the SUs 1 and 2 (glimepiride), the most active enantiomer, (S)-6al (AG-EE 623 ZW; repaglinide;
