  Addition, substitution and deoxygenation reactions of .alpha.-phenyl-.beta.-nitrostyrenes with the anions of thiols and diethyl phosphite: formation of indoles by reaction with ethyl phosphites

  摘要：

  Reactions of excess RS- (R = Ph, t-Bu) with Ph2C = C(SPh)NO2 in Me2SO form Ph2C = CHSR via conversion of the initial Micheal-type adducts into Ph2C(SR)CH = NO2- and Ph2C = CHNO2. In a similar fashion, reaction of (EtO)2PO- with Ph2C = C(SPh)NO2 forms initially mainly PhSP(O) (OEt)2 and PH2C[P(O)(OEt)2]CH = NO2-, which upon acidic workup will yield the nitroalkane or the Nef reaction product, Ph2C[P(O)(OEt)2]CHO. The reaction of (EtO)2PO- with Ph2C = C(SPh)NO2 also produces Ph2C[P(O)(OEt)2] C = N via a perkow-type reaction of the Michael adduct to yield Ph2C[P(O)(OEt)2]CH = N(O)OP(O)(OEt)2 as an intermediate. The nitrile is also formed from Ph2C[P(O)(OEt)2]CH(NO2)2 with (EtO)2PO- in (EtO)2P(O)H or Me2SO at 30-degrees-C and in > 95% yield by the reaction of (EtO)3P with Ph2C[P(O)(OEt)2CH(NO2)2 at 150-degrees-C. Reaction of Ph2C = CHNO2 or Ph2C[P(O)(OEt)2]CH2NO2 with excess (EtO)2PO- in Me2SO or (EtO)2P(O)H forms 3-(diethoxyphosphinyl)-2,2-diphenylaziridine by a process postulated to involve Ph2C = CHN(O-)OP(O)(OEt)2, Ph2C = CHNOP(O)(OEt)2-, and 2,2-diphenyl-2H-azirine. Similarly, Ph2C = C(SBu-t)NO2 and (EtO)2PO- give 3-(tert-butylthio)-2,2-diphenyl-2H-azirine in Me2SO or 2-(tert-butylthio)-3-phenylindole in (EtO)2P(O)H solution. Deoxygenation of Ph2C = C(X)NO2 to form the 2-X-3-phenylindoles occurs in high yield at 150-degrees-C in (EtO)3P with X = H, PhS, or t-BuS while 2-nitro-3-phenylindole is formed from Ph2C = C(NO2)2 in (EtO)2P(O)H at 150-degrees-C.

  A mild method for the deborylation deuteration of arylboronic acids with D2O, mediated by the synergistic combination of a thiol, a Lewis base, and photoredox catalysis, is reported. This reaction showed a broad substrate scope, excellent deuterium incorporation, and functional group tolerance. Therefore, this method is practical for the site-selective D-labeling of bioactive molecules and drug molecules

  A transition-metal-free protocol for the synthesis of non-terminal alkenyl ethers, alkenyl sulfides, and N-vinylazoles from arylaldehydes or diarylketones, DMSO and O, S, N-nucleophiles has been reported. In this protocol, 24 examples of non-terminal alkenyl ethers and 28 examples of non-terminal alkenyl sulfides in 72–95% yields have been synthesized within 5 min. Moreover, 27 examples of non-terminal
