An approach to a macrocyclic lactam designed to bind to a carboxylate anion is described.The diaryl ether 8 was synthesised by Ullmann coupling of the protected 3-hydroxyphenylglycine derivative 7 and (E)-4-bromocinnamic acid methyl ester.Elaboration of an optically pure (R)-tyrosine synthon was achieved by transfer of electrophilic azide to the N-acyl oxazolidinone 12.The synthesis of a model system is also described.

A synthesis of 2-substituted-1,3-dienes is reported which uses silicon as a control element: eight aldehydes were converted into α-silyl ketones by treatment with trimethylsilylmethylmagnesium chloride and rapid Collins oxidation.Addition of vinylmagnesiu

Coupling of (3-chloro-2-methylanisole)tricarbonylmanganese tetrafluoroborate with the phenoxide derived from methyl N-Boc-3-hydroxyphenylglycinate gave the diaryl ether manganese complex (6).This complex underwent regiospecific, stereoselective reaction with Schollkopf's chiral glycine enolate equivalent to give a mixture of dienyl-Mn(CO)3 complexes that were converted in a two-step sequence into the protected deoxyristomycinic acid derivative (12).
A SILICON DIRECTED DIENE SYNTHESIS
Brown, Paul A.,Bonnert, Roger V.,Jenkins, Paul R.,Selim, Mohammed R.
, p. 693 - 696 (2007/10/02)
A convenient method for the conversion of a series of aldehydes into substituted dienes is reported which uses silicon as a control element.
