Calculate Digit Verification of CAS Registry Number 153711-74:
(8*1)+(7*5)+(6*3)+(5*7)+(4*1)+(3*1)+(2*7)+(1*4)=121

Regio- and stereospecific cleavage of α,β-epoxysilanes with lithium phenylsulfide

Cuadrado, Purificación,González-Nogal, Ana M.

, p. 1111 - 1114 (2000)

Trimethyl- or dimethylphenylsilylepoxides react with lithium phenylsulfide to give regio- and stereodefined vinyl sulfides resulting from α-ring opening and Peterson elimination. When the epoxide bears the bulky tert-butyldiphenylsilyl group the reaction

A base-promoted deprotection of 1,3-dioxolanes to ketones

Yuan, Changchun,Yang, Li,Yue, Guizhou,Yu, Tianzi,Zhong, Weiming,Liu, Bo

supporting information, p. 6972 - 6976 (2013/01/15)

An effective deprotection methodology of dioxolanes was developed, affording moderate to excellent yield via a LTMP-promoted reaction in THF, which displays admirable chemoselectivity in the presence of dimethylketal, 1,3-dioxane, 1,3-dithiane, or other acid-sensitive protective groups.
