    • After aqueous workup the aldol adduct (-)-4a was isolated as a colorless oil (>95% by HPLC), which could be carried forward to the subsequent hydrolysis. Alternatively, silica gel chromatography provided the adduct as a white solid from which we obtained single crystals for X-ray analysis. CCDC 828856 contains the supplementary crystallographic data for (-)-4a. This data can be obtained free of charge from The Cambridge Crystallographic Data Centre via.
