Synthesis of Optically Active N-Benzyl-2,4-Bis(hydroxymethyl) Substituted Azetidines by Lipase Catalyzed Acetylations
Guanti, Giuseppe,Riva, Renata
, p. 2921 - 2924 (1995)
Both cis- and trans-N-benzyl-azetidine-2,4-dimethanols 5 and 6 were prepared and submitted to acetylation in organic solvents catalyzed by lipases.Asymmetrization of diol 5 gave the corresponding monoacetate 7, while double sequential kinetic resolution of racemic 6 gave optically enriched diol 6b and its enantiomer as the corresponding diacetate 10a.Optimized reaction conditions furnished 7, 6b and 10a with e.e.>99percent.

The present invention relates to novel oxazolidinones (Formula I): or a pharmaceutically acceptable salt having ring A characterized by N-containing monocyclic, bicyclic or spirocyclic substituents, to their preparation, and to their use as drugs for treating Mycobacterium tuberculosis and other microbial infections, either alone or in combination with other anti-infective treatments.
Practical synthesis of 3-oxa-6-azabicyclo[31.1]heptane hydrotosylate; A novel morpholine-based building block
Walker, Daniel P.,Eklov, Brian M.,Bedore, Matthew W.
, p. 2859 - 2862 (2012/11/13)
Bridged bicyclic morpholines are important building blocks in medicinal chemistry research. The bicyclic morpholine 3-oxa-6-azabicylo[3.1.1]heptane (3a) is of particular interest as a morpholine isostere because it is achiral and shows similar lipophilicity to that of morpholine, based on the cLogP of a derived analogue. The first synthesis of morpholine 3a (tosylate salt) is described; the seven-step sequence begins with inexpensive starting materials and uses straightforward chemistry.

Concise synthesis of N3- and N6-monoprotected 3,6-diazabicyclo[3.1.1]heptanes; Useful intermediates for the preparation of novel bridged bicyclic piperazines
Walker, Daniel P.,Bedore, Matthew W.
, p. 6332 - 6334 (2013/01/15)
Bridged bicyclic piperazines are important building blocks in medicinal chemistry research. The bicyclic piperazine 3,6-diazabicylo[3.1.1]heptane is of particular interest as a piperazine isostere because it is achiral and shows similar lipophilicity to that of piperazine based on the c Log P of a derived analog. A concise synthesis of N3- and N6-monoprotected 3,6-diazabicyclo[3.1.1]heptanes 2d and 2e, respectively, is described. The seven step sequence begins with inexpensive starting materials and uses straightforward chemistry.
Synthesis of chiral non-racemic azetidines by lipase-catalysed acetylations and their transformation into amino alcohols: Precursors of chiral catalysts
Guanti, Giuseppe,Riva, Renata
, p. 605 - 618 (2007/10/03)
Azetidinic mono-acetate 7, diol 6b and di-acetate 10a were prepared with high e.e. using PPL-catalysed acetylations. The absolute configurations of all new enantioenriched compounds were assigned by chemical correlation with known compounds. Mono-acetate 7 was then transformed into 30, an amino alcohol of noteworthy potential interest since it represents an interesting precursor for chiral catalysts, such as 32.
