Application

(tert-Butyldimethylsilyloxy)acetaldehyde is a versatile reagent commonly used in synthetic glycobiology. It can act both as an aldol donor and an aldol acceptor in the stereocontrolled production of erythrose. It is used as an important reagent in the total synthesis of (+)-ambruticin, (−)-laulimalide, (−)-salinosporamide A, and (+)-leucascandrolide A.
Employed in the construction of the key tetrahydropyran subunit in a recent synthesis of the marine natural product (–)-dactylodide.

Given the significance of carbohydrates in life, medicine, and industry, the development of simple and efficient de novo methods to synthesize carbohydrates are highly desirable. Organocatalytic asymmetric assembly reactions are powerful tools to rapidly construct molecules with stereochemical complexity from

[reaction: see text] The enantioselective total synthesis of (-)-dactylolide is reported. The absolute stereochemistry of the tetrahydropyran was established by catalytic asymmetric Jacobsen hetero-Diels-Alder reaction. The remote C19 stereocenter was introduced by a sequence of chelation-controlled Grignard addition and Ireland-Claisen
