  Investigation of the chemoselective and enantioselective oxidation of α-thio-β-chloroacrylamides

  摘要：

  An investigation of the chemoselective and enantioselective oxidation of alpha-thio-beta-chloroacrylamides is described. The alpha-thio-beta-chloroacrylamides can be selectively oxidised to either the racemic sulfoxide or the sulfone very efficiently. The asymmetric sulfur oxidation of alpha-thio-beta-chloroacrylamides is also discussed, with sulfoxide enantioselectivities of up to 52% ee achieved using the Kagan oxidation, and up to 71% ee when the Bolm oxidation is employed. While the enantioselectivities achieved are modest, these are among the most highly functionalised sulfides investigated in catalytic asymmetric oxidation, and the resulting enantioenriched sulfoxides have significant synthetic potential.

  1,3-Dipolar cycloadditions of 2-thio-3-chloroacrylamides with nitrile oxides and nitrones is described. A series of novel isoxazolines are isolated from the nitrile oxide cycloadditions, whilst the isoxazolines generated from the nitrone cycloadditions undergo further ring opening to yield piperidines.

  conjugate addition of a range of carbon, nitrogen, oxygen, sulfur and selenium nucleophiles to the highly functionalised 2-thio-3-chloroacrylamides is described. The stereochemical and synthetic features of this transformation are discussed in detail. In most instances, the nucleophile replaces the chloro substituent with retention of stereochemistry. With the oxygen nucleophiles, a second addition can

  描述了在高度官能化的2-硫-3-氯丙烯酰胺中合成一系列通用的碳，氮，氧，硫和硒亲核试剂。详细讨论了这种转化的立体化学和合成特征。在大多数情况下，亲核试剂会保留立体化学来取代氯取代基。对于氧亲核试剂，会发生第二次加成反应，产生乙缩醛，而对于氮亲核试剂，会在所得烯胺衍生物中发生E - Z异构现象。E / Z异构体的比例可以基于取代基和氧化水平来合理化。
• The influence of reaction conditions on the Diels–Alder cycloadditions of 2-thio-3-chloroacrylamides; investigation of thermal, catalytic and microwave conditions

  The Diels–Alder cycloadditions of cyclopentadiene and 2,3-dimethyl-1,3-butadiene to a range of 2-thio-3-chloroacrylamides under thermal, catalytic and microwave conditions is described. The influence of reaction conditions on the outcome of the cycloadditions, in particular the stereoselectivity and reaction efficiency, is discussed. While the cycloadditions have been attempted at the sulfide, sulfoxide and sulfone levels of oxidation, use of the sulfoxide derivatives is clearly beneficial for stereoselective construction of Diels–Alder cycloadducts.

  2-Thio-3-chloroacrylamides undergo 1,3-dipolar cycloadditions with diazoalkanes leading to a series of novel pyrazolines and pyrazoles. The mechanistic and synthetic features of the cycloadditions to the 2-thio-3-chloroacrylamides at both the sulfide and sulfoxide levels of oxidation are rationalised on the basis of the nature of the substituents.
