Two chiral intermediates, C(1)–C(9) and C(11)–C(17) portionsof protomycinolide IV, were synthesized both from (S)-ethyl lactatevia asymmetric pinacol-type rearrangement followed bydiastereoselective reactions on α-methyl-β,γ-unsaturatedcarbonyl compounds.
脯氨酰内酯IV的两个手性中间体,C(1)–C(9)和C(11)–C(17)部分,是通过(S)-乳酸乙酯通过不对称频哪醇型重排合成,然后在α-甲基-上进行非对映选择性反应而合成的β,γ-不饱和羰基化合物。
