  Reductive Cyclization of Ketones Tethered to Activated Olefins Mediated by Magnesium in Methanol

  摘要：

  The reductive cyclizations of various ketones tethered to activated olefins such as alpha,beta-unsaturated esters, nitriles, sulfoxides, and sulfides were mediated by magnesium in dry methanol in the presence of mercuric chloride. When treated with magnesium in dry methanol at -23-degrees-C all of the ketones except nitrile 9 (42%) and 5-oxa-8-keto-2-enoate 5 (13%) gave excellent yields (79-98%) of mono- and bicyclic alcohol products resulting from carbon-carbon bond formation between the beta-carbon of the activated olefin and the carbonyl carbon. The reaction was accelerated by the catalytic amount of mercuric chloride, although the stereoselectivity was not affected by the catalyst. For all the substrates except 8-keto-2-enoate 3 and 5-aza-8-keto-2-enoate 6, the configuration of the major product was trans between the hydroxy and (methoxycarbonyl)methyl groups. The product isomer ratios were independent of the substrate geometry (E or Z). In contrast to the ketones, aldehydes tethered to alpha,beta-unsaturated esters gave products of simple reduction of the double bond and/or saturated alcohols instead of the cyclized products. When the reaction temperature was lowered, the yields of cyclized product were significantly affected by the production of appreciable amounts of saturated product, but the stereoselectivity was not improved. Under the same reaction conditions alpha,beta-unsaturated sulfoxide 16 gave deoxygenated sulfide 18 (85%) as the major product along with a small amount (9%) of cyclized product 19t. In contrast, sulfone 17 underwent desulfonylation instead of cyclization to give olefin 20 (54%). With excess magnesium (15 equiv), however, alpha,beta-unsaturated sulfoxide 16 gave cyclized sulfide 19t (95%) via deoxygenated sulfide 18. Both 16Z and 16E afforded product 19t as a single isomer. It is suggested that the reductive cyclization of the alpha,beta-unsaturated esters and nitriles proceed by means of nucleophilic attack of a beta-carbon radical anion, formed by initial electron transfer from magnesium metal to the activated olefin, on the carbonyl group. The cyclization of the alpha,beta-unsaturated sulfide proceeds by nucleophilic attack of the ketyl on the olefinic double bond.

  combination of sulfanyl radical addition–cyclization of the oxime ethers and hydrazones connected with alkenes and subsequent conversion of a phenylsulfanylmethyl group to a carboxyl group provides a novel method for the construction of the cyclic β-amino acids. Upon treatment with thiophenol in the presence of AIBN, the oxime ethers and hydrazones smoothly underwent sulfanyl radical addition-cyclization

  A tandem ring-closing metathesis reaction using ruthenium catalyst was carried out to synthesize various fused bicyclic compounds containing both small and large rings. Fast ring-closure of the small ring and slow ring-closure of the large ring resulted in the formation of only one Isomer. Further manipulation such as the Diels-Alder reaction was carried out to prepare a complex molecule containing multiple rings of different sizes.

  Benzoic hydrazides (R = Ph), which are remarkably bench and thermally stable reagents (often up to 230 degrees C), afford intramolecular hydroamination products upon heating at high temperatures (120-235 degrees C). A concerted Cope-type hydroamination event, followed by a hydrazide-mediated proton transfer step of the hydrazinium ylide intermediate, is proposed and supported by DFT calculations. In contrast, a simple modification of the reagent structure (R = Ot-Bu or NH2) favors the formation of aminocarbonylation products at 200 degrees C, and the tatter reaction is shown to be stereospecific.

  Behind the mask: Nitrogen‐substituted isocyanates are rare and their synthetic potential is virtually untapped. Simple masked precursors can form amphoteric amino isocyanate intermediates in situ, and allows the synthesis of complex hydrazine derivatives upon addition with amines. This reactivity was used in a cascade substitution/hydroamination sequence, and in the assembly of azadipeptide analogues
