WebThe nickel-catalyzed reaction of sulfonyl enyne with an exogenous alkyne partners and in situ elimination of phenylsulfinic acid provides neopentylene-fused indane cores. The novel methodologies presented herein were used to shorten the synthesis of neoprofen, a synthetic analogue of ibuprofen, from ten steps to seven. ... WebThe quenching of the 2-lithio derivative of 1-phenylsulfonyl glucal 2.3 with D 2 O yielded the deuterated analogue 2.44; the same 2-lithio derivative on reactions with aldehydes in the presence of lithium diisopropylamine (LDA) generated 2.45 and 2.46. The loss of phenylsulfinic acid from 2.45 afforded the 2-benzylidene- d -gluconolactone 2.47.

By comparison, alkylthiols and arylthiols have S–H BDEs of 87 and 79 kcal mol −1, respectively. Reactions with alkyl radicals on the academic sideWebThis reduction has been known for many years and remains a most simple and elegant way of reducing a triple bond to a ( Z)-alkene with high stereospecificity and chemoselectivity. The reduction with diimide is extremely chemoselective tolerating ester, amide, and allylic halide functionality. on the account of synonymWebafter phenylsulfinic acid addition (Figure S4). Increasing amounts of sodium phenylsulfinate were titrated to a 2 mM solution of S-nitrosoglutathione in the dark. The reported pKa of a sulfinic acid is ~2.828, yet the reaction proceeds similarly at pH 1, suggesting the sulfur lone pair acts as the nucleophile, independent of the protonation state. on the accuracy of timoshenko\u0027s beam theoryWebAn example of a simple, well-studied sulfinic acid is phenylsulfinic acid.
