(R)-2,3-O-Cyclohexylideneglyceraldehyde, a Versatile Intermediate for Asymmetric Synthesis of Chiral Alcohol
摘要:
Grignard addition to (R)-2,3-O-cyclohexylideneglyceraldehyde (IIa) gave rise to column chromatographically separable diastereo alcohols 2 and 3 including highly functionalized and synthetically exploitable homoallylic alcohols 2e and 3e and homopropargylic alcohols 2f and 3f. Compound 3c on functional manipulation gave rise to (-)-coriolic acid synthon 6.
