The generation of dichlorocarbene for addition to olefins has been realized by the use of chloroform and alkali metal alk-oxides4 6 (preferably potassium feri-butoxide), sodium trichloro-acetate,6 butyllithium and bromotrichloromethane,7 and the reaction of an ester of trichloracetic acid with an alkali metal alkoxide.2,8 The latter method, which is here illustrated by the preparation of 2-oxa-7,7-dichloronorcarane, generally gives higher yields of adducts.

Generally, there is no limitation in the 1,3-dicarbonyl compound used. However, several types of these substances are not stable, such as malone dialdehydes or formyl acetic acid. In such cases, l,l,l-trichloro-4-oxo-butanone 96 is an appropriate substitute, since the trichloromethylcarbonyl moiety can easily be transformed into a carboxylic acid ester after the reaction by treatment with an alcohol and a...

The use of extracellular lipases of microbial origin to catalyze the stereoselective hydrolysis of esters of 3-acylthio-2-methylpropionic acid in an aqueous system has been demonstrated to produce optically active 3-acylthio-2-methyl-propionic acid [41-43], The synthesis of the chiral side chain of captopril by the lipase-catalyzed enantioselective hydrolysis of the thioester bond of racemic 3-acetylthio-2-methylpropionic acid (15) to yield 5 -(-)-(15) has been demonstrated [44], Among various lipases evaluated, lipase from Rhizopus oryzae ATCC 24563 (heat-dried cells), BMS lipase (extracellular lipase derived from the fermentation of Pseudomonas sp. SC 13856), and lipase PS-30 from Pseudomonas cepacia in an organic solvent system (l,l,2-trichloro-l,2,2-tri-fluoroethane or toluene) catalyzed the hydrolysis of thioester bond of undesired enantiomer of racemic (15) to yield desired S-(-) (15), R-(+)-3-mercapto-2-methylpropionic acid (16) and acetic acid (17) (Fig. 8A). The reaction yield of... [Pg.150]
