Chan, Wing Hong,Lee, Albert W. M.,Lee, Ka Ming,Lee, Tin Yau
, p. 2355 - 2356 (2007/10/02)
Pyrroles have been efficiently synthesised by a three-step reaction sequence.Michael addition of keto esters onto phenyl vinyl sulfoxide followed by Pummerer rearrangement gave the cyclic key intermediate 3.Mercury(II) salt induced carbon-sulfur bond clea
REGIOSELECTIVITY IN THE 1,3-DIPOLAR CYCLOADDITION REACTION OF 3-METHYLOXAZOLIUM 5-OLATES WITH ACETYLENIC DIPOLAROPHILES
Croce, Piero Dalla,Rosa, Concetta La
, p. 2825 - 2832 (2007/10/02)
The cycloaddition reaction of unsymmetrically substituted munchnones with monosubstituted alkynes has been examined.The reaction affords a mixture of regioisomeric pyrroles.The observed regioselectivity is qualitatively discussed on the basis of the MO-pe
