Abstract
Propargyl silanes with a terminal alkyne moiety undergo a 1,2-silyl shift when activated with electrophiles such as H+, Br+, I+, and PhSe+. A method was developed to trap 1,3-transposed electrophilic centers with various internal O-, N-, and S-nucleophiles in a 5-exo manner. This synthetic procedure provided five-membered heterocycles containing a trisubstituted olefin side chain. The scope of the method includes access to tetrahydrofuran, γ-butyrolactone, 2-isooxazoline, pyrrolidine, and thiolane derivatives in yields ranging from 25 to 85% (23 examples in total). Reactions with TsNBr2 ensured complete (E)-selectivity of the newly formed olefins. Further functionalization of the obtained 1-trialkylsilyl-2-bromovinyl side chain was demonstrated by double-bond geometry-preserving electrophilic substitution and cross-coupling reactions that provided heterocycles with a trisubstituted vinyl moiety.

Abstract
![]()
The 1,5-HAT–1,2-(ester)alkyl
radical migration (Surzur–Tanner
rearrangement) radical/polar sequence triggered by alkoxyl radicals
has been studied on a series of C-glycosyl substrates
with 3-C-(α,β-d,l-glycopyranosyl)1-propanol
and C-(α-d,l-glycopyranosyl)methanol
structures prepared from chiral pool d- and l-sugar.
The use of acetoxy and diphenoxyphosphatoxy as leaving groups provides
an efficient construction of 10-deoxy-1,6-dioxaspiro[4.5]decane and
4-deoxy-6,8-dioxabicyclo[3.2.1]octane frameworks. The alkoxyl radicals
were generated by the reaction of the corresponding N-alkoxyphthalimides with group 14 hydrides [n-Bu3SnH(D) and (TMS)3SiH], and in comparative terms,
the reaction was also initiated by visible light photocatalysis using
the Hantzsch ester/fac-Ir(ppy)3 procedure.
Special attention was devoted to the influence of the relative stereochemistry
of the centers involved in the radical sequence on the reaction outcome.
The addition of BF3•Et2O as a catalyst
to the radical sequence resulted in a significant increase in the
yields of the desired bicyclic ketals.
