A Concise Enantioselective Total Synthesis of (?)-Virosaine A
The total synthesis of (?)-virosaine A (1) was achieved in ten steps starting from furan and 2-bromoacrolein. A one-pot Diels–Alder cycloaddition/organolithium addition initiated an efficient sequence to access a key oxime/epoxide intermediate. Heating this intermediate in acetic acid resulted in an intramolecular epoxide opening/nitrone [3+2] cycloaddition cascade to construct the caged core of 1 in a single step. Several methods of C?H functionalization were assessed on the cascade product, and ultimately, a directed lithiation/bromination effected selective C14 functionalization, enabling the synthesis of 1.

O-TBS-N-tosylhydroxylamine: A reagent for facile conversion of alcohols to oximes
(Chemical Equation Presented) A variety of oximes were synthesized from the corresponding alcohols, alkyl halides, or alkyl sulfonates without using external oxidants. With this simple two-step procedure involving substitution with readily available TsNHOTBS and subsequent treatment with CsF, a range of oximes were prepared including the ones hardly preparable with conventional procedures.

Synthetic methodology for the preparation of N-hydroxysulfamides
A convenient synthesis of a variety of substituted N-hydroxysulfamides from chlorosulfonyl isocyanate is reported. Alkyl groups can be introduced selectively on the N-Boc nitrogen of key intermediates 1a or 1b using the Mitsunobu reaction with alcohols. S
