3- Hydroxy-2-hydroxymethyl pyrrolidin

A rather unusual, and quite specific, Mannich reaction occurs when the pyrrolo[3,2- pyrimidine 14 undergoes reaction with (3i, 4i )-3-hydroxy-4-(hydroxymethyl)pyrrolidine IS and formaldehyde to produce the pseudonucleoside 16 (Scheme 2) <2003OL3639>.

Naturally occurring and synthetic polyhydroxylated pyrrolidine and piperidines have recently received considerable attention due to their biological activities. Barco has used tandem Michael-Henry reactions to synthesize 2-hydroxymethyl-3-hydroxy-4-nitro-pyrrolidines, from which the nitro group is removed to give the natural product, trans 2-hydroxymethyl-3-hy-droxypyrrolidine (Eq. 7.72).91... 

Two new pyrrolidine alkaloids, radicamines A (16) and B (17) [characterized as (2,5,35,45,55)-2-hydroxymethyl-3,4-dihydroxy-5-(3-hydroxy-4-methoxyphenyl)-pyrrolidine and (25,35,45,55)-2-hydrox-ymethyl-3,4-dihydroxy-5-(4-hydroxyphenyl)-pyrrolidine, respectively] were isolated from Lobelia chinensis Lour, (family Campanulaceae) by Shibano et al. the present investigators also demonstrated both the... 

In a similar manner, intramolecular cyclization of the O-stannyl ketyl derivatives 201 and 206, generated from the oxazolyl aldehydes 200 and 205, provides a facile method for the chiral synthesis of 3-hydroxy-2-(hydroxymethyl)-5-substimted-pyrrolidines 202 and 203 and the piperidine analogues 207 and 208 that can be successfully transformed into naturally occurring amino alcohols, (+)-bulgecinine 204 and (—)-desoxoprosopinine 209, respectively (Fig.
