  A Photoinduced, Benzyne Click Reaction

  摘要：

  The [3 + 2] cycloaddition of azides and alkynes has proven invaluable across numerous scientific disciplines for imaging, cross-linking, and site-specific labeling among many other applications. We have developed a photoinitiated, benzyne-based [3 + 2] cycloaddition that is tolerant of a variety of functional groups as well as polar, protic solvents. The reaction is complete on the minute time scale using a single equivalent of partner azide, and the benzyne photo-precursor is stable for months under ambient light at room tempurature. Herein we report the optimization and scope of the photoinitiated reaction as well as characterization of the cycloaddition products.

  iazoles 1 with n-BuLi underwent addition to aliphatic and aromatic aldehydes and cyclic and acyclic ketones. Subsequent in situ thermal rearrangements of the intermediates in the presence of zinc bromide provided one-carbon chain-extended or ring-expanded alpha-aryl- and alpha-heteroaryl-substituted ketones 2 in moderate to excellent yields in simple one-pot operations with excellent regioselectivity

  3‐Aryl‐1,2,4‐benzotriazines were conveniently prepared in moderate to good yields from 1,l‐bis(benzotriazol‐1‐yl)methylarenes with allylsamarium bromide/hexamethylphosphramide (allylSmBr/HMPA). Preliminary results indicate that HMPA may enhance the reducing ability as well as prohibit the nucleophicility of allylSmBr, thus making allylSmBr/HMPA as a promising single‐electron transfer (SET) reagent

  by treating the corresponding alcohol with triphenylphosphine, N-bromosuccinimide and benzotriazole. Under these conditions, the alcohols gave exclusively the corresponding 1-alkyl-benzotriazoles. Allyl and propargyl alcohols also reacted regiospecifically in a typical Sn2 manner, and no products derived from prototropic rearrangement were found.

• Benzotriazole-Mediated Stereoselective Olefination of Carboxylic Esters:  Transformation of α-Amino Acid Esters into Chiral Allylamines

  Diastereoselective trans-olefinations of carboxylic esters 3a-h have been accomplished using benzylic or allylic benzotriazole derivatives la-e to prepare alpha-(benzotriazol-1-yl) ketones 4a-i, for the subsequent reduction of 4a-i, and finally for low-valent titanium-effected dehydroxybenzotriazolylation.(1) N-Protected alpha-amino acid esters 9a-c and 15 thus give allylamines 13a-e and 19 with virtually full retention of chirality. Mechanistic aspects of the dehydroxybenzotriazolylation are discussed.

  Lithiation with n-butyllithium of a variety of benzotriazole derivatives 1a-f and 5a-d, all containing a proton alpha to the benzotriazolyl moiety, gave anions which underwent addition to aliphatic, aromatic, and alpha,beta-unsaturated aldehydes and cyclic and acyclic ketones. The resultant N-(beta-hydroxyalkyl)benzotriazole derivatives 3a-m, 6a-g, 9a-d, and 10a were dehydroxybenzotriazolylated when treated with low-valent titanium to give alkenes 4a-m, dienes 7a-j, and triene 11a, with selectivity for the trans isomers without separation of diastereoisomeric intermediates. This method offers an alternative to the three most frequently used methods for the formation of alkenes from carbonyl compounds-the Wittig, Peterson, and Julia reactions-especially in the formation of tri- and tetrasubstituted alkenes.
