Photochemistry of thiophene-S-oxide derivatives
Heying, Melanie J.,Nag, Mrinmoy,Jenks, William S.
experimental part, p. 915 - 924 (2009/10/26)
Photolysis of substituted thiophene-S-oxides in solution results in the formation of either the corresponding thiophene or furan, in addition to uncharacterized materials. No good rationalization is available for the choice of which pathway may predominat
Magnesium mediated carbometallation of propargyl alcohols: Direct routes to furans and furanones
Forgione, Pat,Wilson, Peter D.,Fallis, Alex G.
, p. 17 - 20 (2007/10/03)
The addition of vinyl and aryl Grignard reagents to propargyl alcohols for the direct synthesis of furans and butenolides from a one pot reaction is described. These products arise from a putative magnesium chelate intermediate 2 upon reaction with various electrophiles. This chelate was also generated in situ from alkynyl lithium addition to aldehydes followed by magnesium exchange and Grignard addition. Thus, the complete substitution pattern for the furan ring may be controlled, as desired, through the judicious choice of substrates and reagents.
3,4-Bis(tributylstannyl)furan: a Versatile Building Block for the Regiospecific Synthesis of 3,4-Disubstituted Furans
Yang, Yun,Wong, Henry N. C.
, p. 656 - 658 (2007/10/02)
By utilising an oxazole-alkyne Diels-Alder reaction, 3,4-bis(tributylstannyl)furan is prepared and its synthetic potential assessed by its conversion into several 3,4-disubstituted furans via Stille-type palladium-catalysed reactions.
