A novel linking-protecting group strategy for solid-phase organic chemistry with configurationally stable alpha-[N-(phenylfluorenyl)]amino carbonyl compounds: Synthesis of enantiopure norephedrines on solid support

A novel linking strategy has been developed for synthesizing configurationally stable alpha-amino aldehyde on polymeric supports. Alkylation of L-alanine methyl ester with 9-bromo-9-p-bromophenylfluorenene, followed by ester hydrolysis and coupling to isoxazolidine, provided N-(9-p- bromophenylfluoren-9-yl)alanine isoxazolidide (5), which was transformed into its corresponding boronate 2 by a palladium-catalyzed cross-coupling reaction with diboron pinacol ester. Boronate 2 was anchored to four different polymeric aryl halides 6-9 in 70-99% yields. Polymer-bound alaninal 1b was then synthesized on non-cross-linked polystyrene by hydride reduction of isoxazolidide 10b. Treatment of alaninal 1b with phenylmagnesium bromide, cleavage of the resulting amino alcohol in a 1:2:2 TFA/CH2Cl2/anisole cocktail, and acylation with di-tert-butyl dicarbonate furnished N- (BOC)norephedrines 14 that were demonstrated to be enantiopure by conversion to diastereomeric thioureas 15 and analysis by HPLC. In summary, we have developed a process by which the 9-phenylfluoren-9-yl protecting group has been converted into a new linker for the solid-phase synthesis and manipulation of alpha-amino carbonyl compounds.

Application of complex aldol reactions to the total synthesis of phorboxazole B

The synthesis of phorboxazole B has been accomplished in 27 linear steps and an overall yield of 12.6%. The absolute stereochemistry of the C4-C12, C33-C38, and C13-C19 fragments was established utilizing catalytic asymmetric aldol methodology, while the absolute stereochemistry of the C20-C32 fragment was derived from an auxiliary-based asymmetric aldol reaction. All remaining chirality was incorporated through internal asymmetric induction, with the exception of the C43 stereocenter which was derived from (R)-trityl glycidol. Key fragment couplings include a stereoselective double stereodifferentiating aldol reaction, a metalated oxazole alkylation, an oxazole-stabilized Wittig olefination, and a chelation-controlled addition of the fully elaborated alkenyl metal side chain.

Transformations of nitrates (nitro esters) of amino alcohols involving both functions 1. Reaction with alkali metal hydrogen carbonates

The reaction of nitrates (nitro esters) of amino alcohols with alkali metal hydrogen carbonates yielding oxazohdin-2-ones and tetrahydro-1,3-oxazin-2-ones was discovered. A large number of both known and newly synthesized nitrates of amino alcohols with various structures were involved in this reaction, and the optimum reaction conditions were found. New oxazolidin-2-ones and tetrahydro-1,3-oxazin-2-ones were synthesized. Two more transformations were found for a few examples. One of the reactions gives nitramino alcohols, whereas another reaction affords polymers.

High transition temperature shape memory polymers (SMPs) by telechelic oligomer approach

This work describes the synthesis and comparative shape memory properties of cross-linked networks derived from epoxy and cyanate ester monomers containing polyether oligomers as reactive shape memory segments. The hydroxy telechelic oligomers viz. polyethyleneglycol (PEG), polypropyleneglycol (PPG), and polytetramethyleneglycol (PTG) are reacted with epoxy-cyanate ester matrix resulting in shape memory polymers with high transition temperatures. The soft oligomer segments act as flexible linker unit which interconnect oxazolidone, isocyanurate and triazine ring structures in the cross-linked polymer. The resultant cyclomatrix SMPs exhibit high transition temperatures 132, 178 and 161 C respectively for PEG, PPG and PTG integrated SMPs. The Eg/E r ratios are increased in the order PEG < PTG < PPG. The PTG and PPG based SMPs show shape retention of 99% and shape recovery of >98% with recovery time <100 s. All the SMPs display good thermal stabilities (both inert and oxidative) above 275 C.
