To our delight (and perhaps some relief), the sulfamate-tethered aza -Wacker cyclization of 10 afforded oxathiazinane 11 in synthetically useful yields and as a single diastereomer. We anticipate that 11 will serve as a key synthon for future elaboration into C4- epi -Bactobolin. Scheme 3.

Sathyamoorthi 2020). In our previous work, we showed one example of ring opening with sodium 2-naphthoxide. While the nucleophilic ring opening of 5-membered cyclic sulfa-mates (oxathiazolidines) with phenoxide and thiophenoxide has been extensively explored (Malhotra et al. 2015; Bar-aznenok et al. 2005; Carreras et al. 2007; Bower et al. 2007;

An organocatalytic cross-aldol reaction of formaldehyde (formalin) with alkyl aldehydes, followed by the Z-selective Horner-Wadsworth-Emmons (HWE) reaction and immediate lactonization, afforded γ-alkylated pentenolides in good overall yields and excellent enantioselectivities. Based on this scalable sequence, five quinolizidine alkaloids were synthesized in a unified and concise manner ...We present protocols for the oxidation of alcohols and aldehydes and for the oxidative cyclization of diols which use a combination of Selectfluor and NaBr. For most substrates, the optimal solvent system is a 1:1 mixture of CH3CN/H2O, but, in select cases, biphasic 1:1 mixtures of EtOAc/H2O or CH2Cl2/H2O are superior.

The use of theta-glass emitters and mass spectrometry to monitor reactions that occur as fast as one μs is demonstrated. Acidified aqueous solutions containing unfolded proteins are mixed with aqueous ammonium acetate solutions to increase the solution pH and induce protein folding during nanoelectrospray ionization. Protein charge-state distributions show the extent to which folding occurs ...
