Easy re-construction of 4- hydroxymethyl -1,3-oxazolidinone system into an isomeric 1,3-oxazolidinecarboxylic acid system during the synthetic trial of jadomycin S aglycon requests us to more precisely re-examine the structures proposed for jadomycins S and T, derived from hydroxyl-containing amino acids of l-serine and l-threonine, respectively. Tangirala; Patrick R. The 4C-Ugi reaction requires an acidic component as one of the building-blocks. Graphical contents list Synthesis of benzyl substituted naphthalenes from benzylidene tetralones by Lorraine M. Whalen; David L. Vander Jagt; Robert E. Royer A convenient and efficient amino of novel highly substituted dimethoxybenzylnaphthalenes, which are precursors to several dihydroxynaphthoic acids, is described.
Whalen; David L. Prior; David F. O MeO O MeO MeO OMe 12 An efficient, short step and high yielding approach of these tetralones will be of great utility for large scale synthesis of several bioactive compounds for their complete preclinical and clinical evaluations. Maguire
A convenient and efficient synthesis of novel highly substituted dimethoxybenzylnaphthalenes, which are precursors to several dihydroxynaphthoic acids, is described. An efficient and straightforward procedure for the Suzuki—Miyaura cross-coupling reaction was studied by using aryldiazonium silica sulfates and sodium tetraphenylborate in the presence of a catalytic amount of Pd OAc 2. Moreover, the synthetic protocol was simple and the reaction conditions were mild. Introduction of the carboxyl group significantly facilitated the removal of the residual benzothiazoline and benzothiazole by washing with aqueous basic solution.
Anderson; Raghuram S. The first total synthesis of hibarimicinone has been achieved. The scope and conditions of the reaction were explored.

The amino acid was efficiently prepared in six steps via a Mukaiyama aldol reaction by a chiral oxazinone and 3-bromomethoxybenzaldehyde. Alkylation of 5-aminotetrazole with 2,5-dimethylhexane-2,5-diol in perchloric acid was found to proceed on an endocyclic nitrogen atom as well as on the amino group, giving 5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-4H-tetrazolo[1,5-a][1,3]diazepine.

Lorenz; Anita R.
Royer We herein report a new synthetic access to o-amino-2,2,2-trifluoroacetophenones starting from commercially available o-amino benzoic acids, which can easily be converted into the corresponding benzoxazinones. Catalytic activity in Henry reactions of the corresponding copper II complex was studied. The rhodium-catalyzed diastereo- and enantioselective Michael addition of arylboronic acids to 3-alkylenyloxindoles has been developed with R -binap as a ligand.

The protocol avoids the use of expensive catalysts, toxic solvents, and chromatographic separation. We achieved the synthesis of a derivative of phenylalanine with a diazamacrocycle on its side chain by macrocyclization of a dichloride on l-DOPA. Multigram routes to 2,3-dihydro-1H-pyrrolo[2,3-c]pyridinetriflate 16, 2,3-dihydro-1H-pyrrolo[2,3-b]pyridinecarbonitrile 20 and 4-chloro-2,3-dihydro-1H-pyrrolo[2,3-d]pyridazine 30 are outlined.
